I go through security in like 5 seconds... It isn't really a hassle... security checks = means to protect air-goers from threats = common people. Police officers = protectors of the people (well mostly)... So in a general sense they both do the same thing... If we reduce security in the airport, we reduce maximum protection = reducing measures taken by police officers in ensuring our protection. To do the latter would be dumb... so too would be to eradicate or reduce the first.
