Only the assertion of a shrink that you "might be suicidal". I guess if you off yourself there would be a noticeable loss of revenue to the local government who must then take whatever action they feel is warranted to prevent this.
The 7th U.S. Circuit Court of Appeals has ruled that it is not a violation of constitutional rights if police break down a citizen’s door, search the home, and confiscate firearms, so long that they believe it is in the citizen’s best interest.
This fits well enough with the ruling in Pennsylvania that the cops don't need a warrant to search your car in an otherwise routine traffic stop. This might actually work out better for the citizens since demanding the police get a warrant used to result in the driver sitting by the roadside in handcuffs for an hour or two while the warrant was obtained. Now they can sit in the comfort of the squad car while the officer on the spot tosses their car. No waiting.
