It's funny; I have seen people that do things like this get flat tires. For some reason, 6 at once.
A valve core tool is pretty cheap.
On a side note if you were to remove the valve cores from someone's tires could that be considered a crime? It is not like the tires are ruined.....so vandalism would be a stretch. You aren't stealing anything if you leave the cores in a conspicuous place.
Tampering? Maybe? At best?
Don't remove them, just loosen them. Then it's not stealing
