I'm curious on your reasoning here. What makes you think truly random search will be sufficient to change their behaviour? frequent enough means not always, hence, they can simply send multiple parties and then odds might be good enough that not all of them will be caught by the random search (again, depends on the frequency of search you left undetermined). What kind of odds do you think will stop a person willing to blow him/herself up?
