Here's another tidbit I found a while ago. In the US, when on private property you must abide by the rules set down by the property owners. So, within a Mall, they can create a rule against anyone taking a photo and they can back that with the law (as in having you removed). However, there are exceptions to this rule. If a public official holds a meeting, speech, debate or whatever else in an official capacity, wherever he/she holds that event immediately becomes public property for the duration of the event. That means they can not stop you from entering (unless you're a security threat) nor can they stop you from taping or photographing the event. Makes sense when you think about it. Found this the same time I found out the fact that when you have a fire on your property, the moment the fire department is notified, control/ownership is transferred to the Chief. It's what gives them the right to order you out of your house and tear the roof off if they need to. Ownership doesn't revert back to you until the Chief okays it.
