What’s wrong with profiling?
The writer uses a robbery situation to show that police use profiling all the time. That is how they catch criminals.
They interview the witnesses and then look for someone who meets the description. This happens all the time when a crime is committed and no one complains.
So we have a crime of illegal immigration. They police have a description. They go out and look for people that fit the description.
I don't see the problem. In fact, the Arizona Immigration law forbids racial profiling. I would work to get a similar law passed here in Nevada before it is too late.
