That is a great plan. Lick 'em and kick 'em?Let's teach our children not to bully by...what...bullying them? Yes, sir...I am going to stop little Johnny from threatening his friends by threatening him with physical harm. Genius! It sounds like you really know kids...they always listen to what we say, don't pay attention to what we do, and can make perfect sense of the discrepancies between the two. Now, I do concede that bit of your plan is a good thing (seriously). Natural consequences of behavior and the chance to redeem yourself for your wrongs is on the right track (detention, suspension, extra work to make up for missed work), but I would also add some restitution to the student harmed or to the school in general to make up for a negative environment...it is actually to help out the kid who did the wrong learn from his mistake as much as it is for the student and/or school. A lot of schools, currently, are pretty good at this. If you ask me, I do not really want to go back to the schools of 50 years ago (not that we can not learn very valuable lessons from them).
An additional comment related to your view of social workers. I challenge you to walk in the shoes of a social worker any day of the week. Especially one that works for child protective services and is on the front lines daily. Overworked, underpaid, and totally committed to the well being of the children they are working for. If you had half the cojones they did, you would think before you made half-cocked statements about how the world should work...
