I didn't imagine you'd stand by and watch as someone was getting mugged or otherwise assaulted, and I'd never ask you to do that. What I was referring to was that you said you were doing fly-arounds to see what you can do in your spare time, which sounds a little too close to vigilantism. The biggest reason we've been able to accommodate for those brought here by the Tesseract has been because there's been a clear balance of power and respect for the local authorities. If you're asked by the appropriate authorities, then I'd see no problem in you getting involved.
Then I'd say that would be an entirely different debate, and none of the answers would be perfect or anything close to it. The closest I've ever been to a similar situation was a year ago...and that panned out differently than I'd have hoped for.
"What if"s are not my concern -- I'm only focused on the here and now, ma'am.
