Now I don't agree with just setting up and stopping everyone for no reason (DWI checkpoint) But, it's much easier to just be nice comply and be on your way , UNLESS you've been drinking , which you shouldn't be doing. So little "tricks" like mentioned is just way to get away with something that's illegal anyway ?? So bitching that these stops are illeagle , but supporting the "tricks" to get away with something illeagle, seems odd to me
