in respect to this
one of the reporters has just said to Teresa May that one of the attackers from Saturday was on a Documentary ( he might have said BBC ?? ? ) on TV last year waving a IS Flag around in a London park, I understand " freedom of speech " yada yada yada but this must point to another attack by someone known to the authorities
I guess even if they are reported, the report ends up on the right desk and put on " the watch list " they are still free to do what they want
