Can you just pause for a second and reflect on the difference between profiling at a security checkpoint backed by overwhelming firepower and at a bar? Again, I gave my scenario as to what profiling would accomplish at a bar--nothing. So please describe what would happen at this bar when it turns away a heavily armed Arab.

And save the weird, incomprehensible, assumption-filled "PC liberals like yourself sue them for trying to protect their citizens" for a different discussion. Just tell me how profiling would have stopped this massacre.
