Do you mean the various efforts to weaken crypto stuff? I don't think I object in principle to law enforcement having access to the information for law enforcement purposes, but we know that any kind of access is subject to scope creep particularly when you lower the threshold for that access. First it's to enforce reasonable laws, then it's to enforce unreasonable laws, then it's because someone bribed a policeman. Not necessarily in that order.
Besides, the main problem with safety on the internet is not that law enforcement has no tools, it's that the crimes cross political borders. You can (in principle) identify the culprit in Russia easily enough when the money is laundered, but how exactly do you plan to bring them to justice?
But even if the police where you live were perfect, handing them the keys to the internet wouldn't resolve crimes committed outside their jurisdiction.
I see why the idea is appealing to politicians, but even they ought to think twice about the risks inherent in third parties accessing their most private communications - given that whatever sides of the political aisles they sit upon they are likely to be much more interesting targets to better resourced assailants than us average schmucks.
It's either A) we The People are completely free and nobody can intervene in any way or B) The Government is a tyrannical overlord that controls every packet that dares to enter the internet.
Absolute freedom never was and never will be a good idea. If we don't at least talk about it, somehow, someday, and maybe quite soon, They will ram it down our throats and we'll end up closer in scenerio B than A.
The internet reminds me in many ways of the international road network. There are clear boundaries and there are checks and, yes, they suck. It's not a complete free for all, yet it's workable. I know this analogy breaks down eventually, but I'm wondering if there's some middle ground here.
I guess I am jaded by some branches of "hacker culture" with a proclivity for taking pride in activities or mindsets - breaking in, finding exploits, destruction - that I don't find particularly palatable without understanding the social and eventual political backlash that will strip away your freedoms faster than you can say "papers, please".
