Let’s check some scenarios:
1) Police puts a mic inside your house, you step on it, and destroy it. Is it ok or not?
2) Police puts a mic on a guy who comes to your house, you find it, and destroy it. Is it ok or not?
3) Police puts a nano-mic (nano-gps) on you, you find it, and destroy it. Is it ok or not?
My answer to all of the above is that anything put on your property without you knowledge is up for grabs and destruction without further notice. Hour, car, or body is irrelevant.
In #2 the object is in your guests possession, not yours. So,no, you can't destroy it. In the other two cases, yes, I believe it is in your possession.
