The suspicious looking individual was wearing a weight vest which adds difficulty and sweat to your routine. My wife and one of my nephews have them.
And of course, there is one more reason he was detained: He is not one belonging to the politically protected species.
That is all.
I wear one around my neighborhood too. Good thing I don’t live in the Caliphate.
I'm surprised they did not automatically arrest the children playing at the park because they were getting in the way of the "religion of peace" doing what they do.

Glad it turned out OK for the Brits though. After a few more of these incidences (weighted vests during outdoor exercise) they will stop sending the cops to investigate. Then the true rulers of the UK will be free to practice what they do best.
