CCTV is not evidence, the shoplifter has to be seen to put a particular product on or about their person, observed leaving the shop with no break in plain sight, pass the last point of payment and only then can I stop them and tell them my job title, where i work, what i saw and ask them to return to the store to answer some questions. We have no cctv but it would never be admissible. anyway, the guards came and they were so covert and professional. smoked the guy out but cos a member of staff walked near to him just before he was about to put 10 paperbacks in his huge sports bag, he left them and left the store. we know who he is now, bastard. hopefully tomorrow he'll try again, we want this Man With Exotic Headgear so badly so we can use the civil recovery option to search his house.
