that is because Israel does not have the luxury of political correctness

we check 80 year grandmother for terrorism
to appease the politically correct fanatics
who would other wise accuse you of "Profiling"

age profiling? 
gender profiling?
worst of all
horror of horrors

Racial profiling

check that 80 year old white blonde Swedish nun for terrorism 
waste of time and human resources
but Political Correctness must be served
