Though bullet proof and self-protective wear matters but they are not solution to death.
However, it gives self boldness and encouragement but it is still not the key factor.
This does not mean security workers do not need protective wear like bullet proof wear and others. Though it matters but not the solution.
If sophisticated machineries and technology could save lives I don’t think that, America and United Kindom would have face the wrath of Covid19 by claiming million of their citizens.
The solution is Jesus Christ, it’s God who saves life but many will doubt it.
