Any self-respecting drug cartel and terrorist organization has been using modern encryption at all levels, from street to the top, for more than a decade now. What criminals would
not be using an e2e chat app nowadays? Truly the lowest hanging fruit, and no fruit above that. The barrier of entry to using a level of encryption that's beyond the capabilities of most law enforcement agencies to snoop on was equivalent to finding a decent software/IT guy in 2010. It's non-existent in 2020. Just open the app store.
This pretty much solves a very serious problem for all illicit activity - secure communications. It's strange to argue that this ought to have no impact on the ability of law enforcement to combat organized crime or terrorism because they should just compensate elsewhere. That's waiving a problem away instead of facing up to it. Of course it's having a big impact, and telling them 'just be better elsewhere' is not gonna work, they'll still push for stupid legislation.
