To be honest, they can be very unnerving o watch in action and for those who are video game fans; think Half Life series; they conjure up not so good images. Terminator series would likely be the most related that the public would freely associate with them, especially video on one of these dogs running across terrain.
by default I have little issue with them, however with the recent focus on no knock raids and such I am loathe to give the police any tool which is more in line with military use. They already abuse the transfer of purely military vehicles to their forces and their SWAT teams long lost any relationship to traditional police
