In all seriousness I find the lack of charges and trials for treason disturbing.
If you swear an oath of allegiance to this country in order to obtain British Citizenship then you should be held to account if you are found plotting against us.
The evidence against several clerics and people like Anjem Choudary is overwhelming and yet they remain free to plot and plan against the state.
It seems to me that we really don't attach any great seriousness to people who have been found to be breaking the oath.
