How do they know what he was GOING to do? Just because a guy is getting ready to lose his job and has guns doesn't mean he is going to do a mass shooting!

Watch the press conference TLC. Wouldn't want to have that tip, not act, and be wrong. Lots of people have lots of guns and face hard times... They don't all get arrested.

Absolutely, as horrific & sad as this is we must all be aware of our surroundings and not sit on information such as this.

This is like the pit bull argument.

Click on mass shooting plot and you will see your answer!

Something does not sound right here, maybe the press conference will clear it up, not sure the weapons are even a issue, but in the world we live in now, it almost makes sense to make sure nothing crazy happens like Colorado

So I read the "mass shooting plot" article. The news media once again has blown this out of proportion. His beef was with his employer and yet according to the news media he was going to go on a massive shooting. Yes, that mole hill became a mountain.

What's that new saying....See something, Say something?? KUDO'S to the AA Cty Police for their QUICK response to this!!

Sounds like the subject made a threat, not planning some massive rampage. If I was in the media I too would gift wrap stories to give them shock effect. The media is GRASPING for anything gun related, to keep the buzz going. Keep the large amount of comments and web traffic pouring in.

Well, if his former colleague was concerned enough to call the police, that's enough reason to check him out. Good call.

He made a threat. Bottom line. Kudos to the concerned, THREATENED employees at Pitney, and kudos to PG and AA police! If something HAD happened - would you say a mountain out of a mole hill? I guess we will never know since he has been found out! Thank GOD. He's rocking a shirt that says "Guns don't kill people, I do", with an arsenal and a threat, it's enough for me. Thanks!

If the guy was in fact going to try and commit mass murder, it's great that the police caught him in time. However, the story as reported on WJLA looked like a cheesy attempt to tie this area into a big national story like the Aurora shootings; headlines regarding this incident have read "copycat" slayings, "suspect in mass killings arrested," etc. First of all, he didn't commit a mass killing, second of all, until more information is learned, how can they say what he was planning to do would be a "copycat" of what happened in Colorado? Again, I'm glad the police caught up to this guy, but the news media needs to get its facts straight before reporting a story, esp. something like this.

Who calls his victims ahead of time? this case is no more than making threats over the phone.

If that is, in fact, the case, the police will now determine that. He has not comitted a crime, only threats. However, thankfully, it is in the hands of the police now.

Did you read the search warrant? He said "I'm the joker, I'm gonna to load my guns and blow everybody up". I mean, if he has 25 firearms and 400 rounds of ammunition and makes a verbal threat - I'll take proactive measures versus being reactive with 12 people murdered.

Why then does he have all of these assault rifles. I mean I can see having the shot guns and pistols, but is there a need to have so many assualt rifles in your possession?

Let's not turn this into a "defend the second amendment at all costs" argument. No one is trying to take away your guns, TLC. What did happen is a guy who's got a boat-load of guns and ammo, a grudge, and an "I kill people" tee-shirt made a threat. And the AA cops were smart enough to stop a problem before it happened. How many lives were saved today?

Some of these comments seem to indicate that it would have been better for the guy to carry out his threat rather than prevent it. They also missed that part that said he was gonna load his guns and blow everybody up. That kind of a threat is good enough for me. Well done, law enforcement.

Some people ought to watch what they say. Had this individual actually taken violent action it could have been devistating. (Not to say that he was going to) And if the police hadn't acted & something did happen, some of the same people would instead be complaining that the authorities were asleep on their feet. How about saying "job well done" instead of perching yourself on a soapbox?!

"Police said that the man did not have a concealed weapons permi.". I would like for one of the writers of this article to explain to me what that has to do with anything.

This is so stupid... this reminds me of the paranoia immediately following 9/11, when every small town thought their water tower would be the next symbol of national security that would terrorists would target. When I saw the headline, I was expecting an investigation where they discovered loads of detailed plans, not an off the-cuff remark.

What happened to "Innocent until proven guilty"? Only under a fascist police state does this guy deserve to be in jail.

Thank Goodness he was stopped by police and the key hear is someone stood up after hearing him make a comment and called the police who acted quickly to prevent a possible killing. That is the difference between this case and any mass killing that has occurred. Someone took the threat as real and made that call before the nut job acted. Now lets stop playing the what ifs hear. Great job to all the police officers involved.

Maybe so. Thanks to the person who called the police and the police themselves we thank goodness will never know what would have and could have happened. In all most every case we hear or read about there is someone after the fact that says he was really acting strange we wish we had called someone or my son pulled himself away from family and friends if only we knew. These are the people who could have said something and maybe like this case shows stopped a tragedy. All it takes is a phone call out of concern to save many lives. And yes it was a big gun collection.

The police did not "nab" the man. He made a phone call that alerted people to call the police. The PATCH yet again has sloppy reporting.

I also saw the search warrant, it said the employer had called him and he started to threaten him over the phone. 10-15 minutes after the employer called him he called the employer back and threatened him yet again. This is only my opinion, but i think after the second round of threats the person started to believe he was in some danger and called police. Again, as stated here by others, he is still innocent until proven guilty.
