A little background: the guys who sent the letter are PIPCU, a new department with funding for two years who are undoubtedly keen to get results quickly and cheaply.
A weirdness of PIPCU is that they're City of London police, not London Metropolitan Police as you'd expect for a department with such a wide remit.
