What caused the Marjory Stoneman Douglas High School shooting?
Liberal government made schools a free fire zone when they made them a gun free zones.
Liberal government made it impossible to incarcerate the insane against their will and require treatment.
Liberal government has refused to enforce existing gun laws because there is a disproportionate number of minorities in our prisons already and that is deemed racist. The 1347 dead and 6594 wounded in Chicago over a 2 year period (2016-17) prove that fact as nothing has been done about it; 94 percent of the offenders are minorities and the arrest and conviction rates are nearly nonexistent.
Liberal government has made the death penalty a joke as for the most part it is seldom carried out and the condemned (Manson et al) remain in jail for decades at taxpayer expense. (If you really want the death penalty to work, try them today, if convicted sentence them tomorrow allow one or two appeals and have a public execution the day after.) That will never happen of course because lawyers make the laws and it would cost them money.
In addition we have been treating normal energetic children and moody or depressed teens with mind altering drugs such as Ritalin, Zoloft and Prozac for decades.
Now the liberals in their infinite wisdom want more gun restrictions instead of allowing qualified well trained teachers to carry in schools to deter crazy people from committing further atrocities of this kind.
According to American Police Beat, the average response time for an emergency call is 10 minutes. The school shooting in Florida took only 8 minutes. The response time of qualified, well-trained teachers could be almost instantaneous, but let's fight it tooth and nail and blame the NRA and AR-15s.
