david u,
I'm sorry that you wouldn't take me up on my offer. If you feel that what you are doing is the right thing to do, then don't go stealth. Be open about it. Tell your neighbors and community. Let your neighbors know that you are protecting your property and family against killer coyotes. Perhaps they can help. Your community has a stake in THEIR wildlife also. Have you addressed this problem with the authorities? What is their take about you taking the law into your own hands? Let the people know walking the streets in your neighborhood that they may want to avoid your area. Let people know that there may be wounded coyotes in the neighborhood, so that they can protect themselves from coyotes that have never bothered them before, but can really be dangerous when wounded.
I'm pretty sure that I know your neighborhood. I've never once heard of a coyote causing problems. People shoot dogs sometimes, but I've never heard of anyone shooting coyotes until now.
