Typical liberal response--oooooh, take away the guns, make us safer!
No, that is not the answer.  
Evidently the homeowner has a problem.  Discharging a weapon at unarmed workers is not a good idea, and he should, by now understand that.  Shooting and wounding two police officers has pretty much sealed his fate.  The situation has degenerated to a suicide by cop, if the guy doesn't surrender.
You liberal ding a lings who would forfeit your constitutional rights for a perceived feeling of security that your socialist failed ideology has demonstrated it is incapable of providing need to understand that YOU are responsible for your OWN safety and security.  The cops come AFTER the fact.
You don't like this country, move.
