The IRS one might not actually be as nefarious as it seems. Drug busts, due to the money involved, require IRS agents on hand. Said IRS agents are required to have a gun, which likely means they need to be trained. I wonder if money laundering and other forms of trafficking that deal with money also require IRS agents. If so, I could see the white hats bringing along some newly trained IRS agents while they're busting the cabal with their human trafficking and money laundering.

Obviously I could be wrong, but it seems like arming a bunch of IRS agents for any other reason is just weird. Maybe I'm just feeling the good vibes and hoping for more.
