Making Laws/Rules to the Lowest Common Denominator

Why was I a very popular substitute teacher?

One reason is this .... if the"room" was unruly I would find the instigator and the agitator.  THEY are the ones who would be disciplined,  NOT the entire class.

Making laws and rules that affect everyone, when only a few are the cause is a LAZY, STUPID, WAY TO GOVERN ANYTHING.

One of the most stupid signs I know of is "NO PARKING ANYTIME".  That's hardly ever the real case.  One of the BEST signs I ever see is in a school zone :  "SPEED LIMIT 25MPH WHEN LIGHT IS FLASHING"
