Enough Gun Laws?

Laws do prevent “bad guys” from having guns. But currently the most effective laws are local / regional instead of national (or consistent).
 
Wouldn’t you agree that inconsistent laws result in effective lawmaking & law enforcement, when discussing physical goods that can easily travel across city and state borders?
 
Because today, a “bad guy” can simply acquire guns where laws are “loose” and move them to where gun sales are more “restricted”.
 
I mean, maybe I’m missing something, but I don’t think adequate laws are in place everywhere. And really; I’m not completely set in this opinion… there’s still some learning I have to do yet. I’m open to learning new facts.
 
But guns cross state lines, and the data suggests a small handful of states are responsible for distributing guns used in crimes both in those states, and in the rest of the nation.
 
“In New York City, for example, nearly 9 in 10 firearms come from out of state”
 
And it’s not all state to state traffic; it’s also city to city (or suburb to city), within states.
 
The city of Chicago gets a large *minority* of guns (40%) coming in from stores *within Illinois* but outside the city limits of Chicago.
 
Two gun shops, Chuck’s Gun Shop (South of the city), and Midwest Sporting Goods (West of the city) supplied hundreds of guns recovered within Chicago city limits in a 4 year period.
 
“[…] most of the guns recovered in Chicago came from outside the state. Only 40 percent of the guns recovered in the city were purchased in Illinois […]” …but not in Chicago.
 
So the laws are not equal from state to state — or even across municipalities within each state — which is one reason I think they are not effective “enough”. Saying the laws are “already in place” seems to ignore our fundamental inconsistency.
 
That’s not even considering the states where laws have been made “more loose” than others. There are still a few common sense laws that could be enacted in many states even if we don’t have a national standard.
 
In Oregon in 2015 almost 77% of gun deaths were suicides and only 20% were homicides. I linked an article below that touches on some specific efforts to “red flag” individuals who might harm themselves (or others). Those laws simply provide law enforcement a means to take quick action if loved ones feel there’s cause to prevent a gun-related suicide (for instance).
 
That kind of “red flag” framework could be applied on a larger scale and might enjoy support from a small minority of Republican lawmakers … someday. Maybe?
