You are probably a fan of police roadblocks too.
There are plenty of other non-obtrusive ways to catch shoplifters.

I took a beating for upholding individual rights.
These folks don’t catch shoplifters much but their presence prevents a lot of them from practicing their craft in the first place. I have no problem with it. It keeps losses down and prices lower.
You really don’t see the difference between a roadblock on a public street and what you see as obnoxious policies in a private business?
One tramples your rights, the other doesn’t.
