Why feel sorry? The person they are aiming at is most likely apart of a massive terrorist organization, and the person was probably planning to do a way more damage than that gun can do to innocent citizens.
Its meant to be a funny little thing, like when your friend graduates from Drivers Ed and your like " I feel bad for any1 he meets on the road "
They aren't aiming at anyone at all, and it's made using 100% private funds (maybe aquired from government contracts, but for different services). The weapon isn't fielded yet (as far as i know), and is just a concept made by General Dynamics. Honestly, it seems like a marketing ploy. If the M2 or the M134 can't get the job done, you don't mix the two together. You call tac air and make a parking lot.
I wanted to insert a hilarious picture. It wouldn't work, and I got lazy. So imagine this. We have the right to arm bears. Then a bear with an AK-47. heh.
