Did the Pharisees have that bad of a memory that they had to use Judas to point out who Jesus was with a kiss?

You have to remember...Most likely, Jesus was being protected with people surrounding him all the time..In addition to this fact, his head was probably covered in the long head coverings that they often wore in biblical days...The Pharisees knew Jesus but could not definitively make a distinction between Jesus and his Disciples for these reasons...
