Yes, that is a very informative video which I have seen previously and find very excellent, thank you very much.
"The US Constitution does not 'grant' citizen rights, so much as it 'limits' government powers"; am I right?
Which would mean to me -unless I'm missing the point somehow- that a so-called 'Constitution-free zone' would mean that the officer has no police powers, not that the citizen has no rights.
Not that it really is a 'Consttitution-free zone', just that they claim it is by spouting a lot of legalistic-sounding nonsense.
But go figure.

I did wonder if they actually ask if you have a cell phone, or how precisely do they find out you have a cell phone.
So they ask, 'Do you have a cell phone', you can say you refuse to answer.

At that point, they don't know if you have a cell phone, and since we're discussing a random stop, I suppose their only way to get their hands on it is to turn a 'stop & question' into a 'stop & frisk'.

That's where I got to wondering, why keep all that data on a device that can be surrendered so easily.
Is there a way to program the cell phone so it never saves incoming or outgoing numbers, contacts, messages, or texts, and so on.

Then one simply keeps a few numbers in one's head, or written down on paper.
From my POV, it does not seem so inconvenient, as I do not yet even own a cell phone; but I suppose for the person who is an habitual one-button caller and memorizes or writes down nothing, my idea may seem too unworkable.

I wonder if they use hard-wired connectors to connect to and copy a cell phone or is it done wirelessly?
Maybe you could make up or buy a 'jumper cable' adapter about two inches long, that has an oddball size at one end, and is permanently glued into the cell phone, so that without a matching jumper cable adapter to readapt it to common civilian or police plug sizes you cannot copy the phone's contents.
And of course your matching adapter is at home or misplaced under the car seat rug.

Seriously, with all the innovations in different plugs, I should imagine there must be quite a number of oddball or misfit plug sizes out there -worldwide- that with a protracted search one might come up with something truly difficult to match up.
Presuming a wireless connection is not possible, which I'm not certain.

Or I suppose someone may say to just encrypt the data in the cell phone somehow.
Or you could just epoxy the cell phone socket so nobody can ever plug into it at all.
Or if you have a steel case for your phone with a combination padlock on it, in a shoulder bag; can they order you to unlock the case?
IOW, if you must legally surrender your cell phone to be copied, why make it easy for them; why not interpose physical barriers which you are not legally obliged to help them overcome?

But I do seem to remember seeing a movie in which the cell phone number was copied wirelessly somehow.

"Whistleblower: Google Chrome Can Listen To Your Conversations"

2. Adware vendors buy Chrome Extensions to send ad- and malware-filled updates:
Adware vendors buy Chrome Extensions to send ad- and malware-filled updates
Once in control, they can silently push new ad-filled "updates" to those users.
One of the coolest things about Chrome is the silent, automatic updates that always ensure that users are always running the latest version. While Chrome itself is updated automatically by Google, that update process also includes Chrome's extensions, which are updated by the extension owners. This means that it's up to the user to decide if the owner of an extension is trustworthy or not, since you are basically giving them permission to push new code out to your browser whenever they feel like it.

To make matters worse, ownership of a Chrome extension can be transferred to another party, and users are never informed when an ownership change happens. Malware and adware vendors have caught wind of this and have started showing up at the doors of extension authors, looking to buy their extensions. Once the deal is done and the ownership of the extension is transferred, the new owners can issue an ad-filled update over Chrome's update service, which sends the adware out to every user of that extension.
