It has been reported that the NSA shares data, including raw data on Americans, with Israel. Unfortunately, what you are concerned about has already occurred.
sharing information, i think is small potatoes. showing them how to get the information on their own is what i fear.
"Hey, check out this backdoor we found. Enjoy"
