If the police were on his property, and had no warrant allowing them to be on his property, the police were bound to follow his orders, not the other way around. They had not secured permission for the staging of their 'operation' on his property. That makes it a taking (even under the abomination known as Kelo v. New London).
But, of course, the police will be 'cleared', as they thought themselves in 'danger'. And the media will dutifully report that, and the rational behind the 'ruling' by the police.
And if they get to court, the judge will rule that police have special rights that protect them from property owners, for 'public safety' reasons.
