Here in the US a lot of us tend to take our private property rights very seriously, much more so than other countries do. I"m glad we do. Blood, sweat, tears etc... into buying and keeping it, its mine, you are not welcome unless invited.
Mornin', Pedro !
I'd like to supplement Jeff's comments above.
Dunno' about how they do it in other countries, the N.Eastern U.S., and don't CARE.
Under the law here in Az. failure to remove oneself IMMEDIATELY from private property when advised of trespass constitutes an ASSAULT.
Waving that creepy thing off a time or two, giving it a chance to get gone, and than blowing it away would stand as reasonable and acceptable behavior in ANY court in this state.
