After a week of unrest across dozens of towns and cities, police have arrested hundreds of those involved.     The former head of counter-terrorism policing, Neil Basu, says some violence has "crossed the line into terrorism" - as courts sit for extended hours to speed up convictions.   On the Sky News Daily, Niall Paterson speaks to our crime correspondent Martin Brunt about how officers are coping with the challenge of policing the violence, and heads to Liverpool where our home affairs reporter Henry Vaughan has been in court with some of those accused of rioting.  Producer: Rosie Gillott  Editor: Philly Beaumont     Promotion producer: David Chipakupaku
