2500 raids, 230 illegal weapons?<p>We could say &quot;Oh, this means there were almost 10 illegal weapons at every raid&quot;, but, they were not evenly distributed, just like raiding every house in a dodgy estate will turn up a lot of illegal items, but most of them will be centered in a small % of properties, so, yeah, for 2500 raids, most of them will have returned nothing.
