Well said Roadtrip
In the hysteria of this thread, the fact that these are highly trained police who are used to carrying arms seems to have been overlooked. Similarly they will only be deployed on specific flights. The Captain will be advised in advance iaw NASP.
We already carry armed police almost daily on UK aircraft when they are accompanying those people who are entitled to armed protection. They come and go with no fuss and the Captain is informed where they will be sitting. There have been no untoward occurences involving these APO's in the past 10 years on UK aircraft.
As stated earlier, they have their own constabulary powers which are outside the ANO. The Captain is only responsible for the
safety of the aircraft and the passengers.
Merry Christmas all
