7/7 was committed by an internal threat. As was the Manchester Arena bombing, the assassinations of Jo Cox and David Amess and attempted assassination of Stephen Timms, the Streatham stabbings, the London Bridge attacks in 2017 and 2019, the Westminster car attack, Finsbury Park attack, 2017 Westminster attack, murder and attempted beheading of Lee Rigby, Glasgow Airport attack, London nail bombings……

But sure, we don’t need internal intelligence agencies at all.
