Not to get into too much boring detail or derail this thread, but there are thousands of people in the Law Enforcement field, sworn officers, who do not fit the description of what you would call a "cop." Local street officers are usually called "cops." FBI/DEA are usually considered Law Enforcement Officers, but not "cops." They don't usually conduct traffic stops or stop liquor store robberies. A cop is a LEO, but a LEO isn't always a cop.
Now back on topic...
Thursday I found a dirty 3XL safety vest. I salvaged the sew-on reflective tape and put it on my new commuter jacket. Tomorrow I get to test it out.
