Its as simple as this...here in OH, theres kinda a small loophole...u dont let them try to sneak an inch of themselves in that door. A trick theyll often pull is sliding a foot in while talking to you, cuz once they do that, legally here uve indavertently given them the right to enter your premesis. You also cant just shut the door in their face cuz then they can get probable cause to force entry, especiallly if its a disturbance call. The owner or a resident simply has to step outside and close the door behind them, then ask em why their there, if youre being charged, if they ask to enter, refuse, then tell em if you arent being charged nor detained that you are simply going to go about ur business and tell em to have a nice day.
