I will be surprised, and will return the favour. They shot towards my home, I have cause to shoot them, and I damn sure will.
Also, don't be ignorant, just because the dog is a pit, doesn't mean it is vicious, nor does letting them run in my yard give someone right to harm them.
Cops are wonderful assessment tools at a HazMat incident.
Send them in with a lit road flare.
If they don't pass out or blow up, it's safe.
