I was waiting to see where this story went, and to hear first-hand from the two people arrested and detained in British prison for daring to want to interview Tommy Robinson, before coming to a conclusion. In essence two people were stopped, arrested and detained in U.K. prison for having incorrect thoughts as defined by the British government.
The story was such an Orwellian outline; my initial skepticism told me there had to be more to these second and third-hand accounts. Alas, unfortunately the facts are as disturbing as initially outlined. (Source)

USA is the only country in the world with free speech protections. The people above were not even detained for saying something. They were detained because the might say something. ABN
