Some one i know had they car repossessed, It was parked in a private driveway with a fence on both sides of the driveway

Someone elses car was parked infront of the car to be taken, They broke into the other car to move it to get the other car, They damaged the homeowners fence and scrached the car before they left it on the street, It was not even put back in the driveway. The repo company came 2 days before but the police were called because they where standing on the fence and looking thru windows in the home, so the neighbors called the police,In which they cursed at the neighbors when they asked itf they needed something The police said they had to wait for the homeowner to come and move the other car. The did not wait they came back 2 days later late at night. Is this legal or should they file a complaint
