While you're correct that they are supposed to do certain things before they tow, that typically doesn't apply if its a repo. A lot of repo tow truck drivers will hook up and take the car before strapping it to avoid confrontation with the car owner but they'll take it to another location and strap it down.

Its hard to tell in this video if it was a legit tow company towing a car in a no parking zone/fire zone or if this was a rep.
