Explanation:
Red herring - misleading or distracting
The expression first came into existence as 'draw a red herring across the trail', which meant ‘introduce some irrelevance’. A red herring is a herring that has been smoked and has therefore become reddish-brown. Since it has a very strong odor, it was used to lay scents for bloodhounds to follow when being trained. But if during an actual foxhunt, a hound came across the scent of a red herring (laid down previously for the purpose of training), it would get misled, lose track of the fox and start following the scent of the red herring
