Let's see if I can help.
For one, I'm asking what people here would do because presumably many of you are experienced concealed carriers. As a noobie, it's interesting how experienced people would feel it's best to respond to these actual real-life situations that actually happened to others, as documented on video.
For two, yes everyone is different, thus the question. I think I got a decent range of insights (and some revealing consensuses) exactly because everyone is different.
Whether the bad guys are different or not is immaterial -- we only know them by their acts: eg. grabbing asses, walking between couples, robbing stores, etc. If there's some relevant detail you think I left out about the bad guys, please let me know.
Three -- (and most importantly) -- touching someone's ass is sexual assault. No, you can't shoot someone for it, but if it's your wife, daughter, gf -- even you -- you should indeed report it. (No one called it "rape", btw.) And following them to be able to convey their location to cops is "iffy" (good point!), but I would want to make sure something is done about guys who grab the asses of random women.
Following a perp to report them happens all the time. I don't think anyone would interpret that as a "jealousy" or "anger" issue if you want to ensure that a sexual assaulter doesn't remain on the streets. If that's the case, then most men have jealousy and anger issues.
...But, again, point taken about "following" being a gray area. I'm guessing that's one of the reasons you believe Zimmerman should've been locked up.
Four -- I'm not a teenager, and it's "empty-handed skills". If you've never heard the term, it's colloquial for being able to fight without a weapon. That is, if someone is pummeling you, first thing to do is cover yourself with your empty-handed skills rather than get knocked out and have your weapon taken.

Anyway -- other than calling me juvenile, thanks for your insights.
