Having armed personnel on the streets not only increase tensions, raises fear and is unsustainable, but it also dramatically changes our way of life.
That would mean they're winning. They're not.
Armed personnel roaming the streets would not have stopped Lee Rigby's murder.
That's a matter of opinion, those two were on the security services radar for years, but they were allowed to preach racial hatred every weekend on the high street & nothing was done for fear of upsetting the the Somalian immigrants who populate the area.
They should have been quietly "slotted" as a warning to the other fanatics who still roam the area & still preach racial hatred.
Using airports, ferries & being in London on a regular basis I'm more then happy to see/support armed police/military on the streets.
STRIKE FIRST & REPENT AT LEISURE.
Just of course a personal view.
