Getting People Killed

Well, it had to happen sooner or later. Some dumbass in Miami, spooked by Coral Snake's absence, got hold of a ray gun and started doing the kind of vigilante crap that gets people killed. Putting aside the fact that ray guns are in no way covered under the concealed carry permit, that is some seriously stupid shit. Contrary to the laws of action movies and comic books, it is rarely a good idea to pull a weapon and stop any kind of armed robbery. Not only do you escalate the situation and possibly provoke the robber into shooting people, but you also run the risk of getting shot by the police when they arrive at the scene of a violent crime and see you waving a weapon. And even in the best case scenario, you still have one more weapon in the hands of a nervous, trigger-happy person than you did before you pulled the gun. Mr. Wild-West-wannabe didn't get any innocent bystanders killed, thankfully, but there was a confrontation. The perpetrator is dead and the vigilante is in critical condition. All for a few hundred bucks in some crappy fast food joint till. Great job, dude.
Now just imagine how the scene could have played out if the vigilante was a superhuman instead of just a moron with a fancy gun. You start off with a basic hostage situation, and then the guy holding the gun notices someone doing something- a shiver of force field, a twinkle of electricity, whatever. Do you think the armed robber is going to spend a minute rationally assessing your threat level, running you through the list of known superhumans? No. He's going to shoot you in the face. And then he's going to start shooting random people that he thinks are looking at him funny, because they might have superpowers too. Even if you happen to be bulletproof, it's dollars to donuts that most of the other people in the room aren't.
That's one of the big reasons I've been so slow to pursue the superhero angle. I can't stop bullets. I can think of a million cool things to do with my powers, none of which would be any use at all against a gun unless I had a five minute head start. And any display of powers at all is an open invitation to get shot in a violent situation. You can't tell by looking at me that I have superpowers, or what kind of superpowers I have, or how strong they are, or whether I'm willing to use them with lethal force. Some random mugger is not going to know who I am. For all he knows, I'm the next Killer Frost, and if he doesn't put a bullet in me he's going to die, fast. And that even holds true for the other end of the spectrum. Not only is assault with superpowers a felony, but it's often a death sentence at the hands of cops who've seen one too many harmless-looking supervillain take out a city block.
