The exact number of turns is impossible to check. Look for a pattern instead.

Every turn swaps you between a horizontal street and a vertical one.

Solution
With no U-turns, every turn switches you between a horizontal and a vertical street. After an odd number of turns you're on a vertical street; after an even number, a horizontal one.
The patrol starts and ends on a horizontal road, so an honest officer's count must be **even**. The two officers who reported odd numbers, **105 and 113**, are the liars. (The reported numbers are only shown in the picture; two independent sources agree on these two.)
About this puzzle
Inspector Chelmey sends his officers to search every street on a map and report how many turns they made. Left and right turns are fine, but U-turns aren’t allowed. Judging by the numbers they report, at least one officer is lying. Mark the liars.
