About two or three years ago I was taken aside when boarding a plane at a London airport back to Belfast by a policeman and held under their terrorism legislation. Being heavily hungover from a night spent funding London's publicans, and a little nervous about flying, I just wanted to board the plane and go home.

Nevertheless, I was questioned by the queue as others boarded the plane, casting nasty looks my way. The cop asked some pretty insulting, at times ignorant, questions. I guess to see if I harboured any anti-British/anti-state/anti-cop feelings. I got the impression if I lost my cool I'd be spending a lot longer in that airport.

I didn't know my rights, that's my fault. Nor did I want to escalate a situation where the odds were stacked against me. I did feel pretty disgusted though, given that I'd done nothing wrong. Even now I feel like I shouldn't share this kind of thing online lest the wrong person read it. I found myself asking; why me? Was it something I said on Twitter or Facebook? Did I just look at him the wrong way without realising?

Luckily he let me go after some thorough questioning and the plane waited for me (although finding my seat was basically a walk of shame). They probably do this day and daily to all kinds of people. And most would never talk about it for fear of receiving worse down the line.
