RE: Would you shoot or not ?
I'd take the shot if i had the concentration level to follow through and it was safe to shoot.I wouldnot shootin a panic or out of desperation though. BTW sounds like you made the right decision by not flinging a hope n' prayer based on the intrusion.
Like others I have been on the receiving and giving end of situations were game has been bumped. Not unethicaljustright place right time IMO.
