Stephen Paddock killed 59 people when he opened fire on innocent festival goers in Las Vegas.
The horrific atrocity is the most deadly shooting in modern US history, and has prompted renewed calls for gun control in a country where it is incredibly easy to purchase firearms.
Pictures obtained by Boston News 25 have emerged showing the semi-automatic rifles found in Paddock's hotel room, as well as spent rounds of ammunition and a hammer.
Under the second amendment of the American Constitution, US citizens are given the right to bear arms – but critics claim this constitutional right is the reason why gun massacres are seemingly so regular in America.
Donald Trump said in the aftermath of the atrocity that he would talk about gun control at some point – but in a visit to Las Vegas on Wednesday, the US President demurred.
His trip to the site of the shooting was the first time he has had to deal directly with the aftermath of a major shooting rampage of the type that have killed hundreds of people in recent years in the United States.
But, during the visit, Trump deflected a question about whether the United States has a problem with gun violence.
“We’re not going to talk about that today,” he said.
Many have pointed out the seeming inconsistencies in US law as to what products might be deemed dangerous enough to be illegal.
Here are a few items that are banned in the US:
1. Kinder Eggs
For European kids, Kinder Eggs are a staple of childhood. Chocolate on the outside, a toy on the inside. It’s a simple delight, but one that Americans can’t enjoy after they were banned in 1930.
A spokesperson for US Customs and Border protection previously said: "While sold in many countries, this product is banned from the US because young children can choke on it.
"Working together at the Import Safety Commercial Targeting and Analysis Center, these partner agencies are able to coordinate and streamline federal efforts to address import safety issues, including the illegal importation of Kinder Eggs."
2. Children’s Books
A Federal court ruling forbids the sale of children’s books printed before 1985, due to the possibility of them containing lead.
Unpasteurised milk can’t be sold between state lines. A further 20 US states prohibit the sale of raw milk entirely. You can’t be too careful, can you?
A favoured delicacy of the Scottish, but you won’t find it over the pond. It’s illegal to important haggis into America because it contains sheep lungs – an ingredient that doesn’t pass the regulations of the US Food and Drug Administration.
5. Bingo games
In North Carolina, it’s illegal to hold a bingo game for more than five hours - unless it is being held at a fair.
Not all cheese obviously, but Sardinian Casu Marzu is banned on US soil because of how it is produced – reportedly made by placing fly larvae into Pecorino cheese in order to speed up the fermentation.
The larvae hatch which in turn makes the cheese a nice, creamy texture - although you’re advised to eat it before the maggots die. Tasty.
7. Mirabelle plums
A healthy sweet treat, but one that isn’t available in the US due to bizarre import laws stopping the French fruit from ever being consumed on US soil. The precise reason for the ban has never quite been revealed.
