Say I'm driving or walking along and encounter a cop struggling - and losing - with a enraged 300 pound thug, or maybe two of them. Well, boys, at my age (pushing 70, arthritis, double rotator cuff tears, etc.), I'm not the Five Fingers of Death I once was....

If it were me or another person in that same situation, I would be justified. If the victim is an LEO, it would seem even more justified, as the assailant(s) would probably be trying to grab his weapon and thus create even more danger.
Summarily: you encounter a cop being overwhelmed and beaten to a pulp by a thug. You're not capable of intervening physically. After quickly calling 911, you draw your concealed weapon, tell the thug to back off, and if he doesn't, you fire. Is that a viable scenario? Input from LEOs and legal eagles would be especially useful.
