Could be something as simple as the locals claiming jurisdictional authority over the situation because they want to "deal with him" themselves. Local PDs bristle enough as it is when the Feds try to horn in on their turf. They'd like it even less if an international organization like SHIELD tried to. For something like the stuff that was happening on AoS while SHIELD was official, they'll either take the effort to dig through that red tape or just go in surreptitiously. For one "bulletproof black guy with super strength, supposedly killing cops"? Not so much.
