Vague? How do you feel about the Fourth Amendment's protection against "unreasonable" searches and seizures?

[H.Akston]

James Madison said, approximately: It is a melancholy reflection, that liberty is threatened both by too little and too much government.

That's what your question reminds me of.

When it comes to searches and seizures, I'm all for giving the police powers as much leeway as possible these days, as long as they profile Arabs properly.

The IVth amendment is vague, with the word "unreasonable", but at least it's talking about a specific practice.

The XIVth Amendment, might as well say - "No State Shall do unto its citizens what the Supreme Court would not do unto its citizens". That wins the prize for vagueness.
