I believe that feds can ask for monitoring capabilities to be included o ISP.
However, they cant ask for an EASY way to tap lines. They cant to ISP to lower its defense just because they dont have money to tap fiber or whatever.

Just standardize monitoring capabilities at ISP hubs. What features, how to get data, etc..
Almost (or all) traffic passes thru those hubs.

but if they want to tap wires on street, they must spend some of fed' money to get the devices....
