Go read Neo-neocon’s post on the dots that weren’t connected regarding Orlando shooter Omar Mateen. Here’s a taste:
We are very sensitive to government intrusion, and I think we should be. But when someone has indeed expressed sympathies with violent terrorist groups and has demonstrated communication with members of such groups, I think ongoing monitoring (particularly of social media, which is not a private but a public thing) is absolutely warranted. If the problem is money, more funds need to be allocated. But the problem seems to not be money, but will.
Money is certainly not the problem, since the NSA has the resources to provide data it gathers supposedly for national security and anti-terrorism purposes to the IRS, DEA, and local law enforcement agencies.
