Shooting the Pit w/a .22 for the reason you gave would probably be a tough sell to local authorities unless law permits it. If it was aggressive or actually attacked you, a family member, some other person then by all means. I don't think any one would blame you. I presented a worse case scenario (Pit attacking my daughter) and asked would I be prosecuted for killing it. I was told that given the reputation of Pit Bulls he didn't think any Judge in Hampton (Va.) would prosecute me. Lets hope stinging his rear end with a pellet will do the trick
