The answer to the question asked will lead to the root cause of this issue.
I can provide a unique insight to something similar going on where I live. Over that past year we have had a rash of Murders in our jurisdiction. The suspects are all ages from 17 to 19. I arrested an 18 year old who shot and killed a kid for paying him $120.00 in counterfeit money for marijuana. Here is what I found interesting.
We regularly monitor the jail calls of these suspects. Each and everyone of them exhibit the same behavior on the phone with their parents. These suspects are in complete shock that they are sitting in jail. They literally cry "Mommy" to their mothers and complain about having to be in jail. The parents conversely assure their child that they will put large deposits of money on their child's commissary account and will pay for the best legal counsel possible.
I arrested another 17 year old who, with his 18 year old buddy, attempted to beat to death another high school kid who they thought told the local police of their low-level marijuana trafficking. The victim had his ocular bone crushed and lost sight in that eye. The suspect I arrested asked if he could stop by Panda Express to get something to eat before going to jail.
I am not sure where this complete disconnect with reality has come from. What I know is that this is definitely tied in with these mass murder incidents in public schools in the US.
