Good Guy With a Gun

Great!! He'll be the poster boy for every gun lobbyists,right wing politician, AK carrying nut case in the country. Not to mention the big smiles on the faces of those parasites at the NRA.
If he is smart he will remain anonymous and stay out of the media. He definitely does not want to become a target of revenge. Sure, the NRA and others will brag about this for a while.
 
Normally, I'm pro-police but after that fuck-up in Texas, I'm glad that a private citizen took matters into his own hand.

There's no doubt that the "good guy with a gun" scenario works from time to time - usually in a large open room setting like a food court of coffee shop where it's easy to identify the bad guy and understand what's going on. The more complicated the setting and scenario, the more likely it is that things are going to get too complicated and confusing for an untrained good guy person to figure out the situation and act correctly and appropriately.

The scenario will be exploited by the GOP and NRA. A similar situation in TX some years ago occurred when no one was able to fire back as TX law at the time banned concealed handguns and no 'good guys" could carry. That episode gave impetus to a raft of "concealed carry is just fine in this state" laws throughout most of Red State America.

This incident and Uvalde will allow the NRA and GOP to spin "When the cops are cowards, you gotta rely on the Glock you carry in your jeans next to your dick and save your wife and kids yourself.".
 
Reminds me of that NYC subway guy. The thugs were going to beat him up and rob him. Instead, he shot them all.

When Gabby Giffords got shot in the chaos a good guy was gun almost got shot by the cops. And often these public shootings are very chaotic. Too many blokes think they'll be Clint Eastwood eating a hot dog whilst they draw their handgun and pop the bad guy. Real firefights are as stressful as anything you can imagine.

Yes, this bloke in Indiana did a great job thankfully. Good on him. It's an argument for more training for those with conceal carry though too.
