They threw pine cones at you? Here's the plan.
Gather up as many pine cones as you can, you'll need atleast 150. Gat a rather tight net from Home Depot or somewhere and get string. Follow see kids to and from school so you can see their exact route to and from school, or anywhere they go for that matter. Find somewhere they pass on a daily basis where you know for sure they walk, but make sure it's under a large, bushy tree. (Optinal: dig a hole in the ground, with a circumference of around 3 feet to 5 feet). Now take a ----- a big one so it blends in with the pine comes and just set it aside. Tie the bad of 150+ pine ones (and shit) to the tree above where ey walk. Find a way to camp in the tree higher than the net, when they walk by, spin on them and when they look up cut e net ripe and the 150+ pine ones AND your shit will plumet on these fucks. Then while on the ground, tie the, all up to the tree, and viciously whip the pine ones at them. Ey will be heless at this point ties to the tree, so leave the knife used to cut e right near eir feet, just so they have no way to escape. Oh make sure your wearing a mask, it'll make things more legit and give them more of a scare. Good luck
