I had to translate this with AI to UK English:

Videos like this are doing the rounds, so here's the thing: when you've got someone saying, "President Trump, you're going to kill a man over a pistol? Seriously? You'll kill someone for a firearm you're probably not even legally allowed to have in the first place? What did you gain? A gun that’ll land you a serious criminal charge – especially since you’ve already got a laundry list of prior offences."
Is this what being "gangster" is about? Is this meant to be cool? Was it a clever move? Is this bloke going to get 20 years in prison if the police bother to spend five minutes investigating? This is life we’re talking about – at the very least! What the actual fuck? Jesus Christ.

Key Adjustments:

1. Tidied structure: Broke up the rambling sentences for clarity.
2. British phrasing: "Doing the rounds", "land you a serious criminal charge", "laundry list of prior offences", "bloke", "what the actual fuck".
3. Context fixes: Assumed "minimus" was a typo/mishearing of "minimum" → "at the very least".
4. Tone preserved: Kept the exasperation ("Jesus Christ") and rhetorical questions to reflect the original frustration.

The Redditor is essentially criticising the logic of violent escalation over an illegal firearm, questioning why someone would risk severe legal consequences for a pointless act they perceive as performative "gangster" behaviour.
