In a search for continued relevance...
Brady Campaign, in a desperate quest for continued relevance, announces it will protest "bad apple" licensed dealers. "Bad apples" are to be measured by the raw number of BATF traces tracing guns back to them.
1. Licensed dealers can sell only after the buyer passes a background check (and their first target is in Illinois, where the buyer must pass another check and get a Firearms Owner ID Card as well). So it stands to reason that the targeted FFLs are not selling to criminals. More likely, to legit buyers who had their guns stolen by criminals (the trace still goes back to the dealer who made the sale, not to the thief).
2. Traces are not the same as guns used in crime. BATF encourages police to trace every gun that comes into their possession, including, for example, guns recovered from a gun burglar.
3. Brady is using only raw numbers, not percentages of sales. If traces are randomly distributed among dealers, the largest dealers in the area will have the most traces. Just as, in my city, if cars used in drive-by shootings were traces, the biggest numbers would come from the 2-3-4 biggest auto dealers in town, and very few from the more numerous dealers with 20-30 used cars on their lot. (The city has likewise 2-3 major gun dealers, about 5 medium ones, and probably dozens of small ones, Back when getting a license was simple, it probably had hundreds.).
But why worry, so long as it generates some media coverage and maybe adds a few members to a a foundering organization.
