Great. And you're always free to do so. When they ask to search your person or belongings, you should be happy to know you can consent to a search.
Problem is, the issue here isn't just your rights. It's the rights of others. And those rights aren't yours to sacrifice.
Those that would trade liberty for security deserve neither.
I appreciate your position, and for the record, I am a far right wing sort of guy. I wonder if you're aware of AlQ's boast that they will kill 4 million Americans. Perhaps you would like to have this chat after they've set off some nukes in major cities. Will you then be so ready to defend your right to keep your trunk sealed (except for probable cause) or be asked by a cop in a random stop to see your license? After all, we know we have numerous terrorist cells in this US right now, and over 10 million muslims living here, precious few of whom have expressed outrage at the attack on the WTC. As a matter of fact, many of these moderate muslims were dancing in the streets celebrating the collapse of the towers. Need I say more???
