He recently wrote up a post titled If I May Offer Some Advice.... . Here a quote:
You stop a bad man by making a decision. That decision is all that will matter until the future of everything being over arrives. Give no yield, no quarter, no pause. Do nothing less than be victorious. There is no shortage of bad men in the world and there will never be a shortage of such men. But they, the creatures that go bump in the night, the wolves at the door, are thwarted by decision and decisive action.RTWT
It's not caliber, capacity, polymer nor steel that overcomes the evil of this world but rather bravery.
Be brave. Be Brave. Be Brave.
