And why do the law enforcement agencies do nothing? Because the politically powerful will call them bigots and fire them. Its a political problem, not a law enforcement problem. It certainly isn't because we have too many freedoms or aren't monitored enough.
I have heard authorities from the US and the UK, claim they lack the manpower to surveil suspects.
It takes several people, working 8 hour shifts, 24-7, to surveil one person.
So every time an Abdul or an Omar is turned in, police would allocate say 8-12 people to that one.
The UK has 23,000 suspects. They don't have enough police and security forces.
Alternatives include 1. deporting them, 2. locking them up, 3. killing them, or 4. doing nothing beyond listing them.
Option #4 is currently in operation. Manchester, London, Orlando, Ft. Hood, Boston, San Bernardino, etc. are the price paid.
Price is paid by ordinary folks going about their lives. The alternative is to quit politically correct speech, credit to Trump for this.
