It is the “checking” that is troubling and worrisome. The sign itself was self-explanatory. The SS did not need to go to the guy’s house. They could have just checked a lookout list or police records. If the SS doesn’t have the commonsense to figure this out, then it is troubling. Why waste an agent’s time going to the guy’s house?
The REAL villain in this whole mess is that effing cop. He should be suspended and evaluated for competence to perform his job. In addition, that citizen should contemplate a lawsuit against him and the police force.
