When you commit an act which is both against the law and against the policies of the organization you work for, you have zero expectation of protection by that organization and if fact, that organization has an obligation to assist law enforcement in every way possible in prosecuting you.
That Columbia isn't providing that assistance raises red flags to me.
When a 7-11 gets robbed, do the police have to have a warrant to get the surveillance video of the store? The answer is no.
If seizure of this tape isn't warrant worthy, and Columbia serves it up anyways, I'm sure some lawyer can talk their way into some money.
Pure nonsense. In a case where a crime is committed in a public place where there is no expectation of privacy, there is absolutely no liability in turning the tapes over to the police.
