I believe this only refers to CASH deposits.
I realized that a while after posting, so in this particular instance there isn't a big risk. In the end though I don't think it matters if we're talking cash or potato chips. "Suspicion" is pretty much the same as no proof. If a police officer points at you and yells "Witchery!" that shouldn't be enough evidence to tie you to a boulder and toss you in a river. But as it is right now, a law officer can point at you and yell "Drug Criminal!" and take everything you own.
I agree that is dumb, but to answer the question posed in the thread title: No.
Nothing to worry about.
I'd agree that statistically, the chances of getting involved in a situation where your assets were seized is unlikely. But it is alarming nonetheless. I've thought about this a lot lately, because over the past several months, we have traveled by car a couple hours from home to look at used cars listed for sale by owner in the bigger cities near us. Consider these facts:
a) I'm carrying cash. Usually right around $10K. I'd like to take a cashier's check made out to the seller, but since I'm looking at more than one vehicle, I take cash. Plus, as many mustachians will point out... paying in cash can often yield a good deal.
b) I'm driving an older car, worth hardly anything. One that a cop could reasonably be considered a "burner". Meaning one specifically driven so little value is lost if the vehicle is confiscated.
c) The cities to which I travel are in different states than where my car is registered.
If I were pulled over for a traffic violation, those items together would be more than enough for law enforcement to declare it suspicious and seize both the cash and the car!! In a way, I think mustachians are more likely than others (except those actually dealing in cash and illegal items) to find themselves in this situation.
