if a newspaper (in this case the daily Mail) can send a reporter and a camera man out to Calais to investigate the escalating violence by illegal immigrants after a spate of 'highway robberies' involving British holidaymakers.
Why cannot the authorities also have a team of police officers out there, complete with a camera (for evidence) and the power to make on the spot arrests?
Could the reason be that the French are not prepared to participate, since it would mean them using up their own judicial resources in trying to convict and imprison these criminals.
