I think it's normal on one hand that El Al uses armed
guards to protect its aircrafts and passengers, and
as Toda wrote: it's better to have loaded guns than
unloaded while dealing with hypothetical terrorists. On
the other hand, it's sure that having its own security
guards gives the impression El Al doesn't trust the
professionalism of the local police...I don't really care
to know El Al people carry guns, I mean if you fly
to Israel from any airports in the world, be sure to
see soldiers or local special units carrying machine guns!
It might be a little bit frightening but as long as they
don't bother you and they protect you, who care ?
If you go to Paris at this time, be sure to see lots of
soldiers patrolling the streets to prevent bomb attacks,
it's the same...a matter of security! For the information,
the Americans do the same for their flights...I mean at
least in Belgium, they use to have their own security
guards and they even carefully check the cleaning
ladies washing the toilets on board...so....Sorry if you
don't like it or are a little bit frighten (that's normal,
I definitely understand you...!!!...) but it's also for
your own security, you never know how many crazy
guys would dream to blow up an Israeli aircraft...
By the way, a lot of countries who suffer(ed) from
terrorism apply(ied) such methods at home and
sometimes abroad...India, Sri Lanka, Saudi Arabia,
Lebanon, Jordan, Syria, USA, France ("Vigipirate"),
and so on....
