An anonymous reader points out comments from Mark Rowley, the UK's national police lead for counter-terrorism, who thinks tech companies aren't doing enough to prevent terrorists from using their services. He said, "[The acceleration of technology] can be set up in a way which is friendly to terrorists and helps them ... and creates challenges for law enforcement and intelligence agencies. Or it can be set up in a way which doesn't do that." Rowley wouldn't name which companies in particular he's talking about, but he added, "Snowden has created an environment where some technology companies are less comfortable working with law reinforcement and intelligence agencies and the bad guys are better informed. We all love the benefit of the internet and all the rest of it, but we need their support in making sure that they're doing everything possible to stop their technology being exploited by terrorists. I'm saying that needs to be front and center of their thinking and for some it is and some it isn't."
