The problem is that you, who presumably lack legal training, are drawing some conclusions from your experiences that aren’t quite accurate.
If they proceeded to pat everyone down, then either:
[ul]
[li]They had probable cause to believe a crime had been committed, and that you were one of the criminals; or[/li][li]They had a reasonable, articulable suspicion that a crime had been committed AND could point to specific, articulable facts that gave them reason to worry about their own safety; or[/li][li]Their brief detention and pat-down was illegal.[/li][/ul]
Now, what you told the lawyer may well have been more in-depth and detailed than what you’ve related here. And based on some detail that you’ve omitted in your narrative here, but provided to your lawyer, he may well have seen something in your story that justified the pat-down. You, not knowing the significance of that fact, omitted it here.
Based only on what you’ve said - that you were in the middle of a rather loud, annoying group of drunk people - it may be that the cops had probable cause to believe you were drunk in public, that you were disturbing the peace, or that you were guilty of some other arrestable offense. If this were so, then they could legitimately search you.
But that’s slightly different from your original situation. In your original, you said that if officers see a group of kids acting up in a McDonald’s parking lot or people of suspicious nature lingering around some place, they could, without more, frisk them. That’s not so. In order to frisk them, the officer must be able to identify a specific fact or facts that made him concerned for his own safety. He cannot say, “I was just being cautious,” or “Our policy is to frisk all people we approach,” or “They were of a suspicious nature, and they were lingering around.”
You see the difference?
There’s a forum devoted to posting your opinions about things. This isn’t it. I know you posted what you believed to be factual information, and that’s not wrong. But having now learned (hopefully) that the factual answer is a bit more complex than your personal experience and analysis would have suggested, I hope you see that the factual correction was in order.
Illinois v. Caballes does NOT stand for the proposition that if you refuse a search, the canine unit can be called out. Again you miss a subtle distinction.
Caballes holds that a dog sniff is not a search within the meaning of the Fourth Amendment. Period.
If you refuse a search, the police may use a dog to sniff your car. They may not detain you in order to effect this search. So if the police have to keep you in place to call out the canine unit, they may well have detained you illegally.
So, two scenarios:
1: You refuse a search. The dog is already at the scene, and while the officer is writing you a ticket for improper lane change, the dog and his handler walk around your car. The dog alerts on the truck, and the cops force it open, find bales of weed, and arrest you.
Perfectly legal.
2: You refuse a search. The dog is not at the scene. The officer directs you to wait while the canine unit is aclled to the scene. Well after the the officer is finished writing you a ticket for improper lane change, the dog and his handler arrive, and walk around your car. The dog alerts on the truck, and the cops force it open, find bales of weed, and arrest you.
Excellent candidate for a suppression motion. Once the citation was issued, the cops had no reason to hold you. Your refusal of their request to search doesn’t give them any additional grounds or reason to hold you.
