Let’s say Derek gets his way, how would it even work. Former presidents have protection for life so you couldn’t stick him in general population to meet Mr Motivator etc.
Best you could ever hope for is house arrest.
But think about it, rightly or wrongly Trump still has about 16 million supporters who probably own one or more firearms. That’s a rather large army to piss off regardless of the law of the land etc.
Maybe, Trump and BJ should share a cell ?
Don’t forget, if Trump thinks there is any chance of him sharing a cell with the home boys then he will be on a plane to sit beside Putin in cold but safe Russia and beyond all jurisdictions including Sir Kier and Co.
Derek, the Queen has always been above the law and so is any other individual, family or not if they in her presence unless she agrees they can be removed and arrested. As the law stands, the Met Police could be in the same room as her and Andrew with a warrant for him to attend court, she can tell them to leave and/or have them removed and nothing they can do. Unless someone is brave enough to change some laws etc.
