Emblems or icons?
I find lots of great SVG icons that are often Creative Commons or public domain by Googling, for example "police.svg" and "fire.svg".
There are also LOTS of interesting icons on

Is there a place that I can get generic emblems, that are legal to use, such as fire and police department emblems, that I can edit as needed?
