If I may start, Mr. Chair, it really is about being intelligence-driven. Again, with 1.5 million containers, 4.5 million trucks and 1.5 million railcars, you can't scan everything, and it's not effective to do so, so it's about being intelligence-driven.
You referred to auto theft. With auto theft, the vast majority of the vehicles we're recovering are based on either intelligence referrals from police of jurisdiction or our own intelligence targeting, and then technology is leveraged to do those searches. The starting point really is about being intelligence-driven and about targeting.
I'll let Jennifer talk about the technology.
