When you spike consumption in response to lower prices, the prices just go back up.
As with any commodity, this is only true if supply is static or falling while demand rises. The reason gas prices are currently falling is because supply of available oil is rising, largely due to new sources being made available.
or even simply returned to the public in the form of a rebate
Can you provide any evidence of when this has ever happened with a tax was applied to a commodity? In reality, any surplus will be retained by Big Oil. Lefties need to quit trying to hurt the middle class and working poor with all of these proposed "progressive" taxes that are actually completely regressive, disproportionately affecting those who can least afford to absorb them. How about stripping Big Oil of their subsidies for starters? The Democrats could have easily done this during the first half of Obama's first term, when they held the House, Senate, *and* Presidency, yet they chose to leave those surpluses intact.

It's also important to remember that not all inner city gun violence is officially "gang-related" (as in, involved someone who was ACTUALLY a member of MS-13 or some other Gang (capital "G") that's being followed by the researchers). Here in the Baltimore Metro area, the rate of handgun violence is orders of magnitude higher in the city compared to the surrounding suburbs, and the motives are almost always drug-related (even if those involved weren't actually part of an official "gang"). Of course, both Chicago and Baltimore have some of the strictest gun laws in the country . . . clearly the answer is to tighten those even further and ignore the root causes of the violence.
