But that isn't what happened. Nobody has been arrested and put in prison for such claims. All of the people sentenced were sentenced because they were rioting or they were calling for violence which came as a result of the theories.So the grounds on which you want people sent to prison is because they've theorised that the killer is a Muslim and claimed most terror attacks are carried out by Muslims? Wow...chilling! What if both of those things are true? Scary, scary times.
The moral of the story is you can say whatever you want but there are boundaries. You're not going to get done for repeating tittle tattle that goes around the pub but you will get done if you shout it on a megaphone outside of the court where the guy you're shouting about is on trial... This is what Tommy Robinson is now in prison for.
You're also likely to get done if you don't like migrants and so readily believe misinformation that a murder was done by a migrant and so proceed to call for riots or go and smash up the streets in the name of it.
