I suspect you could also use an unregulated trebuchet to launch something over a fence, or perhaps an unauthorized weather balloon with a payload to drop something on your neighbor's lawn from altitude. Or a slingshot (although those might be illegal within city limits). The notion of a serious "security gap" is farcical because any reasonably intelligent person could come up with a number of clever ways to outwit fences and exclusion zones.
