my chime in on the subject... fwiw.
I live in one of the biggest cities in the country, and have noticed within the last few months that the local PD and PD at the institution that I work at have been making changes to their uniforms and vehicles. The uniforms were the first thing I noticed... from a light blue button down top and black pants, to an all black uniform. I asked one of the officers that I speak regularly with what was up with the change... his response - "Homeland Security is giving us funding to match up with other departments."
A couple of weeks ago, I was walking in to grab lunch when three city officers were walking out, and I nonchalantly asked "whats up with the new paint schemes on some of the cars?" (they have changed from blue and white to black and white) One of the officers responded that there was no announcement, and they kind of just showed up with no real explanation. He was hesitant in his reaction and seemed uneasy with the question... I will admit that I was fishing for an answer, so any hesitation would seem exaggerated.
My point in all of this... the whole idea of blurring/blending the municipalities through funding by DHS is concerning.
