Actually no, the author isn't wrong, just badly stating. Although IP is in
packets, they normally follow the same path. However the Author is
referring to ATM which by design breaks even an IP packet into 53 byte
chunks and sends it via any and EVERY path that is available where it is
reconstructed at the other end. (Roughly speaking.)

Packet switching is what ATM does, not what IP routers do.
Yes, you are correct that it can be monitored at the ingress point, or the
egress point. But that's not always in a jurisdiction that is suitable to
FBI activities :)
Think of the amount of traffic that passes THROUGH the USA network as it's
pretty much the "center" of the Internet routing world.

I do agree.
