Good point about twitter etc., mick. It`s highly possible that some of the filth put on twitter came from places other than the UK - in which case, it can make criminal investigation of offences revealed more complicated. Global media (social media platforms) don`t exactly lean over backwards to assist police in identifying suspects - in these circumstances police often face frustrating and time consuming process, sometimes even downright obstruction.
Social Media needs to up its game and take on more responsibility for the vile vitriol abuse placed on its websites day in day out. HMG needs to do more to "persuade" the web giants to become more accountable.
