Justification For No-Knock raids?

Hey, cops are perfectly justified in using force to stop you from swallowing your drugs.

1. You're destroying evidence.

2. That's the very act the drug laws made illegal - so they're stopping *another* crime from being committed!

3. Public safety. Drugs have been deemed bad, therefore they are saving you from harming yourself. Its better the be harmed by another than by your self.

Let's see how long before 2. and 3. are used to justify no-knocks.
