Crimes in which handguns are used are more likely than other crimes to result in fatalities.
Conclusion (therefore)
There is no need to enact laws that address handgun crimes as distinct from other crimes.
Evidence
The majority of handgun crimes don't result in fatalities.
Evaluate
Just because most handgun crimes don't kill people doesn't mean we shouldn't have distinct laws about handguns.
Most people don't die from cigarette smoking, but a lot do! And so we have laws. Most people don't die from going over the speed limit on the highway. But a lot of people do! So we have laws about that.
Even worse for this argument is that the author's second claim seems to undermine her conclusion, since she tells us that crimes with handguns are more likely to be fatal than crimes without!
Goal
At a minimum, the correct answer should reflect the essence of the orig flaw,
If the answer is going to reflect the whole structure, it might also contain that counterpoint:
Counterpoint: Things with X are worse than those same things w/o X. Premise: Most things with X don't lead to something terrible. Conclusion: We don't need to handle X in some special way.
