What are your suggestions to our leaders to make this country safer? We are like sitting ducks!

If I have to rely on our elected leaders I think I'll pass.

That being said better situational awareness when you are out and about
Having a good active shooter plan/drill in place. Yes in CA they said they did do that, but only once a month. Even some of the video initially showed people talking about it being a drill etc. to me that's a major no-no. If you're going to practice it practice it like its for real.
For me and my family. I'll be carrying wherever I go(that's legal).

Crying damn shame though that we even have to worry bout stuff like this. Maybe reality is catching up with us (United States). We are not immune to bad things happening.

For starters I would recommend that the gun-free zones be eliminated if for no other reason than it would confuse many of the evil ones MAJ David Vermillion
2nd leaders should make it clear what is unacceptable and not wince when it comes to naming names.
3rd leaders should promote behavior which benefits communities - sharing with those less fortunate, helping those with disabilities including veterans, the elderly and children.
4th local leaders should promote the concept of community groups to talk with each other openly, report suspicious behavior, and work with the police and not become vigilantes.
5th leaders should reinstitute the concept of neighbors looking our for neighbors.
6th leaders should promote communication and trust between police and the communities to improve relationships.
7th leaders at all levels should lead, accept responsibility for all that their subordinate do or fail to do. Freely give credit to subordinates for jobs well done.

I wonder what DHS and Federal Agencies are planning.
