Can you post officers in uniform on duty on my space?

Question

do i need the officers permission to post on my space

Answer 1

Yes you can and No you don't.

Answer 2

Yes you can do this. You do not need their permission. However, if the officer or his agency sees it, they may request that it be removed. The agency wants to be represented in a positive way, the officer should. It depends on the picture really. You may also take the officers safety into consideration before doing this.
