1. Yeah, it looks like 2017 will be many time higher than normal at this rate. Still would like any data experts to compile... https://ucr.fbi.gov/crime-in-the-u.s/2014/crime-in-the-u.s.-2014/additional-reports/human-trafficking-report/human-trafficking.pdf

Largest FBI bust ever was in 2015 and a mere 150 arrests. http://m.washingtontimes.com/news/2015/oct/15/fbis-largest-ever-human-trafficking-sting-leads-ov/

Ps, only data I've seen is 2000 to 2015 total FBI arrests of ~4,000 (date range may be off by 1 or 2 yrs) - either way, that means we may be looking at arrests many times higher than the average.
