Police often find themselves in high-stress, high-stakes scenarios—facing unruly drunken mobs, drivers stuck in cars about to explode and knife-wielding maniacs.

This series of videos from ad agency Tinker Taylor for the Scottish Police Federation, a professional trade group, wants you to consider how you'd handle yourself in a cop's shoes. The ads work hard to build the sort of suspense that will actually make you feel uncomfortable. They do a pretty good job of it, too—particularly the first brutal spot below.

The personal details about the officers help anchor the ads. The only question is whether they could have done it a little more quickly. The ads clock in at between 1:45 and 2:30, which means what you might do is nod off before they get to the kicker.

Warning: These ads contain violence and may be upsetting.
