Are our laws selectively enforced in an unjust fashion and manipulated to fit the desires of it's enforcers?

Well, they gave me this old coat
Said "It'll keep you mighty warm
It'll see you thruogh the winter
It's your 'By God' uniform!"
So I wear it everyday
And I sleep in it at night
Now it's twenty shades of ray
And the waist is shrunk too tight
And the bottom's caked and muddy
And the buttons are half gone
But just like you and me
This old gray coat wears on
And when I die in this gray coat
I'm gonna' march through heaven's door
I'm gonna' walk up to St. Peter
And tell him "Send me back for more"
Cause I'll be damned if I'll just sit around
While you boys win the war
Cuase even when I'm dead
Shot full of Yankee lead
There'll be part of me keeps hangin' by a thread...
Of this old gray coat
When I think of all the places
This old coat and me have been
Through the fat and lean and inbetween
Double quick through thick and thin
From the ballrooms down in Richmond
To the top of Marye's heights
From Manassas to the Wilderness
And a hundred other fights
Now the collar's torn and tattered
And the elbow's worn clean through
But, buddy, in a pinch
This old gray coat will do
And when I die in this gray coat
And when they come to bury me
If they commence to sheechafyin'
And singin' "Nearer, Lord, to thee"
Well, be damn sure I ain't just sleepin'
Cause I flat out guarantee
That even when I'm dead
Shot full of Yankee lead
That the toughest part lives on in every shred
Of this old gray caot
You can cut my throat
You can sink my boat
But you can never stop this old gray coat
When my bones you tote
When that's all she wrote
I'll fight on inside this old gray coat
Cause when I die in this gray coat
I'm gonna march through heaven's gate
I'm gonna walk up to St. Peter
And tell him "Send me back for more"
Cause I'll be damned if I'll just sit around
While you boys win the war
Cause even when I'm dead
Shot full of Yankee lead
There ain't nothin' that I'd rather wear instead
Of this old gray coat
This old gray coat
I'll go down in this old gray coat
This old gray coat

Yes and No, for a whaft of reasons. Opinion .....My first opinion is that laws are passed to protect, guide, compel, unify and improve the quality of life, safety of our community not to alienate one or many from their rights. A good law leaves no room for interpretation. I site the recent florida tragedy and pubic sentiment (not my opinion). Manipulation of the laws is not acceptable depending on the nature of the manipulation. If a law cannot stand on its own and preserve ones rights, it needs to be repealed or amended. Laws and enforcement are two different animals. Keying in on the words “enforced in an unjust fashion” if the meaning of unjust suggests unjustified a meaningful answer, or opinion would require a specific law, if it was clearly written, its purpose and intent were known and appropriate enforcement (checks and balances) were administered. People enforce laws so personality, opinion, priority, strategy, or agenda can play a role. A problem I see that arises is personal frustration or perspective may cross the line which compromises everything including the intent and purpose of the law. Unjust selective enforcement might be inadequately staffing a high crime zone or neighborhood. Unjust selective enforcement might be posting speed traps for citation revenues, on interstate highways that local drivers don’t often use. Unjust selective enforcement might be labeling a group or certain attire as the likely offender of a crime. Unfair and selective enforcement would be responding to one group with more vigor than another. Justified selective enforcement can be rightfully appropriate under certain circumstances.
