Called it

If you bet that Parkland was suddently going to mean advocacy for increases in "security" spending, you are correct!

"It clearly does raise the bar. Are we spending enough?" asked Rob Pezzella, director of school safety for Worcester Public Schools. "You have to reexamine what your priorities are."

That's from this WBUR article, which otherwise has much more to do with guns around schools and notes this:

It's worth noting that some such security measures were in place at Marjory Stoneman Douglas High School in Parkland, and that alleged gunman Nikolas Cruz had been disciplined for bringing firearms and accessories onto campus. Like other shooters before him, he wasn't enrolled at the time of the killing.

You're not going to police and gadget your way out of this one.
