Not to me directly, but to people close to me. Last year a pit bull attacked the family next door to my in-laws (we are good friends with this family). Dog came to their door step following one of the kids in the family he lived in, and when my friends opened the door to the doorbell the pitbull lunged in the house, snapped towards the baby and then proceeded to almost kill their cat. Cat is seriously fubar'ed now and lucky to be alive. Mouth doesn't work right. Poor thing. Anyway, animal control, police, blah blah pit bull is apparently taken away and put down.
Here it is 6+ months later, and the same pit bull is back and comes to the back yard of my friends and my in-laws. Attacks and nearly kills my friend's dog (they thought it was dead at first), and attacks the lady on the other side of my in-laws from my friend's house. That house has a police officer in it, and he shoots at the dog but misses. Dog keeps coming in and running out, they finally get it with pepper spray and it goes back across the street. Definitely same dog.
Freaking animal control is useless. Comes out 2 hours later, tells the people who were attacked that if he didn't see it it didn't happen and it's just hearsay (

).
Feh.
