"Some of that might be due to the fact that we have more detection capability now than we did in the past, and then our ability to defeat them has improved. Whereas a year ago, almost every one that was detected was not defeated, now about a quarter of the ones that we detect we’re able to defeat"
So if they're routinely "defeating" now, someone is presumably picking up the pieces and analyzing, right? Or does "defeat" mean we pressed the jam button and it went away?
