Questions for a US Dealer

A US dealer disapprovingly writes of the foreigners:

"The failure of governments and law enforcement in foreign lands to eliminate looting and wanton destruction ..."

Tell us, has your OWN government and law enforcement eliminated it in the US and territories under their control (eg Iraq in 2003)? Is there no wanton destruction of petroglyphs, ancient burial sites and sites producing collectable pots and lithic items in the US? To what do you attribute looting and destruction back at home, and is it in any way different to what happens in other lands driven by the same mechanisms? So how would you deal with it in the US?
