If you're using Google you can advance search and tune your results. I dont use it often so i cant say how well it actually performs (especially for sites updated daily).

College or like Library of congress catalog searches can also be timeline searched as well I believe.

You can yes. They have a massive catalog so that would likely be the best place to start. I've searched it like 1 time so I can't give any tips on refining search parameters, but definitely check it out.

Give it a try. If you go to advanced search, you can set a range for publication years. And try police and training for keywords (or subjects).
