Countering child exploitation is an extremely important issue. It's a tough job and encryption makes it harder. But making encryption insecure is counter intuitive and has negative impacts on digital privacy. So poking a hole in encryption, while it can assist with countering child exploitation, can also inadvertently be helping, for example, tech-enabled domestic abuse.

Hopefully DHA understands this and thus have thrown it back at the tech companies to come up with a solution for law enforcement.

I know we would like to think of the exploitation of child labor as some relic of Dickensian fiction, but the bosses still find ways to exploit. I've had many students over the years who worked jobs under management that forced them to work long hours, always at the expense of school work, etc. The policies today seem more concerned with immigration status than academic success.
