The use of a popular phrase.
Don't worry about.
As the artist your job is to be the free flowing font of creativity, regardless of its source. We all find inspiration from somewhere, only prejudice says what is acceptable and what is not.
That said, you make what appears to be 3 statements in the poem and offer no resolution to it, there by naturally robbing it of flow.
It seems you are not given favorably to rhyme.
Is this by choice? I know many that decline to rhyme, when doing poetry so i would understand if that's the case.
1. Guns do not kill people People kill people
2 . Usually the feeble minded weasels
3 . Get caught with a pistol Without a license I mean, what is this nonsense?
Each of these statements could easily have been understood from your first statement and even the title of the poem if it had one.
So instead of making the statement, try and bring people along for the journey of the thought process that you had to take to arrive at your decision that is your current belief.
Provide baser, factoids, easy to grasp concepts and if possible make them easy to read OR eye catching.
Something like this
A Question of honesty
Do Guns have the flaws,
that man from birth draws?
What a great error in specification,
to make in personification.
How can an object glean or tilt,
show remorse or be assigned guilt?
Indeed. how much nobler is man,
to stand and accept what he can.
Do not hide from truth or find comfort in lies.
Being forced to see honesty, only when a child dies.
Accept accountability, put the fault where it belongs.
Then you have hope to right the true wrongs.
This was a quick one, but hopefully you see what I'm trying to say.
The flow of the last 2 sentences is off, can you tell me why?
I didn't try and fix them.
