Lockdown, or Lockdown Mode, is when a public school building is literally locked down so that the Police, as well as the Great Drug-Sniffing Dogs, can search - without a warrant - lockers for drugs and other Contraband Items. And before you ask, yes it is constitutional. I am so sorry.
1. During the annual lockdown mode, we must turn off all the lights in the classroom and not move a muscle; if we are seen in the hallways we are automatically a suspect.

2. Many students question whether this Torture violates the fourth amendment - as there is search and seizure going on without a Warrant - but I'm afraid that you lose many constitutional rights when we go into our schools.
