My impression is that it's only because the English won't let them.

A grassroots unarmed anti-terrorism movement modeled on similar anti-crime movements could significantly reduce the impact of terrorist attacks.

Unfortunately, the English mentality of a passive citizenry that leaves their personal safety to the government, in the hands of professionals, has undermined such grassroots organization; so, there's nothing left to be adapted from anti-crime to anti-terrorism let alone incentive to start from scratch. This also applies to Manchester which while it didn't deserve what happened and didn't want it to happen; nonetheless, was an enabler by just being English.

Now you know and knowing is half the battle. MI6 probably just shakes its head at MI5 and a docile citizenry that doesn't care to change it.
