one hears this said over and over and over again; but with little or no substantiation. the ONLY part of cast lead where this claim actually has any credence is during the bombardment phase of the operation. but even there, as viable hamas targets became exhausted, israel's selection of targets became less focused. but the ground invasion, during which, i'm sure, most of the alleged war crimes took place, there is absolutely nothing "obvious" about any effort made by the idf to avoid civilian casualties. instead, it's the opposite that tends to be most evident in its aftermath. so much so, that only a mental midget could miss it.
