There have been numerous instances of photographers and others going about their normal activities in non-sensitive, everyday locations, yet being stopped and treated in a completely disproportionate manner using this power as the justification.
Well, now we can see just how effective all of that has been, thanks to this neat summary in a tweet by Channel 4's Krishnan Guru-Murthy:
"Out of 101248 police stops under Section 44 anti-terror powers there were 0 terror arrests."Zero terror arrests! He then goes on:
"But 506 'non-terror' arrests. success?"(That's half a percent of 'em)
<sarcasm mode on> Well, that makes it all right then! <sarcasm mode off>
