I'm fine with others attacking me..... in a tank if I'm at TT. Its even named "Tank Town" for gods sake, not "bomber alley". As I said, I don't care if there are GV bombers, just leave TT alone.
I see absolutly no point to bombing GV's that aren't affecting your game play other than getting kills. IMO, the fight should be what matters, not how many kills you get.
If its really as simple as you say, then up a flack at TT, go up near the fighting (most of the time, thats where you will need the flacks), and try to kill all of the planes that try to bomb you, or survive their runs. Unless you prove this, then you can't really say thats all there is to it.
And if you manage to deter (thats what flacks do, they don't STOP, they only deter) or kill all of the bomb****s that attack you, theres a decent chance that a tank kills you instead.
As to CAP's, we've been over this before. You're not going to stop the pissed off tanker that doesn't care if his P-51 explodes as long as he gets the guy who killed his tank.
