Aw, the data doesn't say this at all. In fact the data is a mish mash, as it figured the number of laws the states had. No indicating of what the laws were about and no indicating of causal effect.

Not only this, but the "researchers" said they were trying to show the results they got. Ths indicates to me that they configured the data to effect that result. They also got their data from the Brady Organization.

It smells to me.

If we don't count our blessings
We are just wasting our time
