And the neighbour didn’t want to report anything for fear of being labeled a racist.
So, the truth is that rather than acting responsibly, the neighbour was intimidated. He would have been racially profiling and that has been deemed discrimination.
Political correctness regarding racial profiling and fear of being called a racist has resulted in the death of 14 innocent people. If the neighbour had “said something when he saw something”, things may be different.
That fear has been carefully planted and reinforced by media and governmental actions.
The most recent example: The Ahmed the "clock" maker staged bomb hoax that was designed to provoke a report that could then be publicly and relentlessly attacked as "islamophobia" by the media and government.
