Even in Canadian protests the police have been caught sneaking in trouble-makers with rocks and black ski-masks. If they didn't create the panic they wouldn't get paid for solving it.

Considering that the Turkish government is trying to make the protestors look bad so they have justification for going overboard in their earlier treatment of them, it's more likely that plain-clothes police officers looted those stores and overturned the cars.

When something violent and destructive happens, look at who did the last such thing.
