yep. I'm guilty of doing it once upon a time before I knew better. Confronting in yard is a stupid decision about a dozen ways. If they are in the yard, its a call to le. but when they come inside...
Oh, I'll throw a defense out to balance my opinion: he could argue that anyone running from the police and towards him WAS a threat to his life... not entirely unreasonable.
(this just for something to type. state of NY is going to get a few license plates out of this guy)
I doubt it. There better be specific, articulable reasons as to why he is a threat to your life rather than just a big scary man running from the cops in your yard. Cops get in foot pursuits over a $5 shoplifting just as they do over a home invasion.
