How about people on the receiving end? It is absolutely no secret that the use of DU ammo in Kosovo by NATO forces in 1999 led to an increase in the cancer rates of the civilian population, as well as some military units (most notably the Italian ones). It is no wonder either, DU is pyrophoric (i.e., burns on impact, spreading DU dust in the impact's environs) and should banned just as (even more than) cluster bombs and mines.
