A week before that, the FBI bought 19 DJI drones. These were all P4P birds, through which the FBI wanted to train new remote pilots. In its solicitation letter, the FBI writes:
This is a sUAS produced for the consumer market that combines all the Evidence Response Team Unit (ERTU) requirements: ease of use, high camera resolution, obstacle avoidance, and is relatively low in cost for new and learning remote pilots.
The DJI P4P is the only commercially available consumer sUAS to combine all the required capabilities at an acceptable cost.
The FBI solicitation letter further clarifies:
Other available sUASs were not acceptable, because their sensor resolution was not sufficient, the aircraft lacked collision avoidance technology, or their cost was prohibitive.
