Can police take away props, costumes, video cameras?
If you have a permit and are complying with the terms of the permit, the police must respect your right to do what the permit says. This includes using props and masks. Otherwise, police have discretion to confiscate items and you will have to challenge it after the fact. If the cops characterize your property as contraband (illegal in itself, e.g., pot), you wont get it back. If they say it aided your `crime (maybe a gasmask), theyll institute forfeiture proceedings and youll have to fight them on it. Or theyll just throw it away. Either way, ask for your stuff back & do it quickly.
