Spicerack - // They originally arrested him for ABH, peter.
Probably realised that wouldn't stick so changed the charge.
(bit like when they prosecuted him for contempt of court) //
Suggesting that the charge 'wouldn't stick' rather adds to 'Tommy Robinson's perception of himself, that the world is out to get him.
The reality is more likely that the police make an initial arrest based on what they perceive the offence to be, and when it is analysed, a more appropriate charge is decided on, based more on the correct application of the law, rather than the desperate need to jail 'Tommy Robinson'.
He's only that important in his own mind, and the minds of people who think he is a 'hero'.
