You can't deal with mass migration "on an individual basis".
That will totally fail.
Its like defending your country in a war by 'individually catching enemy soldiers and sending the police to arrest each one."
You are a moron.
"Here come the tanks across the Israeli-Syria border. Quick, call 911 and have the drivers arrested."
To stir up hatred of whole groups based upon the actions of a few of its members is evil, wrong and should be opposed by all right thinking people.
Again you are a moron.
A mafia only needs a handful of hired killers, 'enforcers', or CAPOs, leutenants etc., and the rest are just ordinary infrastructure, non-criminal support and smokescreen.
According to you, the argument of organized biker gangs is valid.
Biker gangs are just harmless motorcycle clubs that collect for charities.
Only individual bikers should be arrested for their personal crimes.
There is no mafia, there is no biker gang, and there is no Muslim Terrorist organization.
They're all individual freedom fighters and individual criminals, but misunderstood.
Throw out RICO, and bring in Chamberlain for President.
There was no danger until Hitler was provoked by being 'offended' by British conservatives.
