[Marvel/DC] How do authorities manage attempts at superheroics gone wrong?

So lets say hypothetically that I'm a D-lister hero wannabe with the power to create gadgets, lets also say that attempting to stop a burglar trying to rob a bank my air gun proved too strong and rather than incapacitating, blew out his brains and splattered his brain matter all over the people I was trying to rescue.

Given this turn of events, how would the authorities proceed in sorting out the mess? Would the Justice League/Avengers get involved? Is there a chance I can still clear my name and become a superhero? And what are my chances if I tried to hide the evidence of this little accident?

Also lets say that hypothetically while trying to escape my smoke grenade ended intoxicating the people I was trying to protect, how screwed am I?

You're a vigilante.  You're treated the same way as a regular guy with an overly powerful weapon.  

If you're a part of an organization such as the Justice League/Avengers or of interest to them, their lawyers will argue on your behalf, but you will be prosecuted to the full extent of the law.

It all depends on whether the Jury buys your "hero" defense.
