Narrative:

On departure from dfw ATC vectored us close to VFR traffic at 6500 ft between dfw and ftw approximately 9 mi west of dfw. We were restr to 6000 ft about a 270 degree heading when the cessna turned to the right and passed within a half mi to our left and 500 ft above causing 2 RA's on TCASII. After given a frequency change I asked departure why the cessna was there in orbit. He stated it was for law enforcement. Before leaving frequency I heard 2 other aircraft receive vectors and altitude restrs to avoid him. I recommend that the departure corridor be kept clear of such traffic. Our flight encountered a moderate wake turbulence event while at 6000 ft after passing the traffic. We would not have encountered it in climb. The wake was from a heavy B767-300ER to hnl who was 13 DME ahead.
