Sorry, but UK police are the absolute worst when it comes to do with anything related to Muslim terrorism and tracking departing/returning jihadists who join ISIS.

ISIS 'vacations' for wannabe terrorists is a big status symbol for Muslims in the UK.

Add to that the way the UK police fail to handle Muslim clerics who openly push hate and death upon Jews in Muslim street protests, or the high rape numbers, forced groomings of non-Muslims young girls to serve as prostitutes, it starts to build a pretty damning picture of the UK police and what they tolerate under their noses. 

Tommy Robinson has been a big and open critic of them, and he's been given no protection or receives no investigations into threats on his life, even though he's been attacked by Muslim bullies numerous times and his life is threatened on a regular basis. It's a police responsibility to protect him when threats are made on his life but they just look the other way.

The UK has a huge problem with their police.
