Does "a person on a leash" make sense？ Hi, friends! I make up a context below for your better understanding. Suppose a convict is escaping arrest, and he's so shrewd and levelheaded that the police feel trapped in a situation where everything they have to do are follow, as the convict is always a step ahead of them. How would you define this kind of scenario? Does "the police are on a leash" make any sense? Or do you have any phrase or idiom in English to express it? Thanks in advance!
