Man halts robbery by four armed men at bar, kills two, but business had posted sign banning concealed permit holders from carrying

This is an interesting case where a frequent and well-known customer stopped a robbery, but apparently the people who work at the bar and the other customers can't identify him to police.  Presumably this concealed carry permit holder knew that he wasn't allowed to carry in the business and wants to avoid an possible criminal penalties.  I know one person who undoubtedly wishes that she had violated the prohibition against carrying a concealed handgun in a bar when Tennessee used to ban it.  From KHOU in Houston:

Just after closing around 2:30 Saturday morning, four armed men barged in at EJ's Place demanding money.

Instead, a customer inside the bar, which is located on the 16500 block of Kuykendahl Road, pulled out his gun and started exchanging fire with the robbers. He shot and killed two of them while the other two ran. Once the heated exchange ended, the patron left, too.

"We're still trying to determine who he is, and why he left the scene," said Harris County Sheriff's Sgt. Robert Spurgeon.

Harris County Sheriff's deputies are looking into whether the same robbers held up a gas station on Cypresswood earlier in the night.

Most folks driving by EJ's Place Saturday afternoon thought the patron there was in the right.

"He has his right to protect himself and his family and his friends," said Charles Webb. "It's just unfortunate something like that happened." . . . 

Another longtime customer said that the patron who killed the robbers always stays until closing to walk the female bartenders to their cars. The friend said the man would never start anything, but would always protect his friends. . . .
