Three teenagers drove through the front wall of my home last year. Does that count?
In any case, Harry did have an arsenal. A sword of the cross, a staff, blasting rod, force rings, that nifty shield bracelet, his coat, a 44 Magnum, a shotgun, a temple dog and Little Chicago. Not to mention a talking skull, various illegal substances and that nifty little summoning circle. Plus his redoubt in the Rent a Shed place.
You need to up your wards. There's a house in my hometown that has reflectors on their fence because of how often cars ended up in their front yard. I can't remember if more than one ended up in their living room.
Unless you have a .50cal, guns are unlikely to be of assistance in that situation.
I'm ready for him to have another better arsenal. Crafted by him. I'm not counting anything given to him.
Never let your guard down, when you think they are at the safest, they aren't. Trust me on that, and not one should ever witness the result.
I've seen the result. Wasn't anyone I ever knew, but it's still not fun. Honestly, I'm much more worried about the non-firearm dangers they introduce themselves to. The oldest
tried to antagonize an alligator. There were kids I grew up with who did that sort of thing and turned out fine with all their fingers and toes, but they knew what they were doing. My niece, not so much.
