i heard gunwalker was a program under Bush that actually had guns with tracking devices inserted used to find gang headquarters for LEO.
True and it was a massive failure. The batteries in the tracking devices were depleted before they could be utilized.
The gunrunning program started in the Bush administration was shut down almost immediately when it was determined that they could not trace the guns as well as they thought they could. When the Obama administration‘s atrocities with “fast and furious” became known, the media (up to its usual tricks) said that it was a program that started under the Bush administration. They were very different.
