Here's an idea: Have a nondescript van parked in a good surveillance location to observe the car which is being "tagged". When the tagger puts to zip tie on the door, at least 4 Aryans jump out, bundle him/her/zim/zer/they into the van. Drive to a remote, pre-planned, rendition site. Begin interrogation but using a tight zip-tie on the tagger's Most Precious Organs of Procreation whilst using a scalpel to open the skin to expose nerve endings. Apply electricity to nerve endings and begin questioning. Finally dispose of the tagger by removing eyeballs, cutting out eardrums and cutting off ears, pull tongue out with pliers and cut off at base, even with the uvula and cutting vocal cords. Remove hands and feet with surgical precision, using a propane torch to swiftly cauterize stubs. Release the defenestration subject on a street corner. Exit the area and go directly to IHOP for breakfast waffles with strawberry sauce, etc.
