Border and School shootings are real problems, but they cannot even be discussed w/o becoming politically charged. Increasing awareness of students to thwart these things before they happen would be the only thing you could do without discussing politics.
The meth issue in the PNW is a good one, particularly how to spot these dirtbags. How to secure a construction site of materials these meth heads are stealing and turning in for scrap. Maybe having all the scrap metal recycling depots have some sort of security cameras that could be provided to authorities to help build cases.
How to make sure the Sudafed stays out of their hands with ID requirements, sales limits to individuals, and what not for purchases might be a direction to take. Oregon put the stuff behind the pharmacy counter. Not many people liked it, but I suspect a lot of meth heads are now recorded on cameras purchasing their base chemical product because they get it from the pharmacy. It would be interesting to investigate into this stuff since so many places that carry these products also have the recording media with the information.
Any effort to consolidate this information and investigate the repeat purchasers of said sudafed type products would be interesting and could be a big move towards a real solution. However, that's a big can of worms and becomes a political issue simply by trying to attain all the video data. Facial recognition software would be helpful. But then again, this would likely drag it out into the political arena rather quickly.
