I can't see any problem with this. Also in Sikh temples, you have to cover your head and take your shoes off when entering the main room where the prayer takes place. This is merely a sign of respect.
Saying that the police should be able to walk into a mosque/temple and not show a simple sign of respect as a gesture, even though they don't follow the faith themselves, is quite ridiculous.
