The Salt Lake City Police SWAT team is spending this week, searching for "the best of the best" -- in Utah law enforcement -- to join their public safety team.

Of the dozens that applied for positions, 34 were invited to the weeklong tryouts.

But it took less than a day for 4 of them to drop out, when they were unable to complete the rigorous obstacle course in the required time.

Physical and mental exams are scheduled to continue throughout the week.
