They can for sure review footage back at least 6 months. Anything of evidentiary value is burned to disc or otherwise archived so they retain it for years.
I've gotten stuff approaching $1000 in one pull from numerous stores, and several occasions. Been back since and no one was looking for me. No PD activity on FB or local news or anything so I doubt they'd be rolling through footage for you. It's fairly time intensive to scour video like that.
