The latest mass shooting to shock the United States into a wave of grieving was the catastrophic incident that happened on Feb. 14, 2018, in Parkland, Florida. This sad mass murder was carried out by a lone gunman armed with an AR-15 assault rifle, which he used to murder 17 high school students.

As the media continues to rage, and communities continue to real, Democratic lawmakers introduced a newly minted gun control measure as a response. If it becomes federal law, the measure would ban individuals from owning the AR-15 assault rifle, among many other weapons that the law classifies as assault weapons.

Thus far, Republicans have strictly opposed the proposed law while Democrats are supporting it. Gun rights advocates oppose bill as well, while pointing out that the AR-15 should not be on the list of banned weapons because it is not a fully automatic rifle.

It's important for any gun or weapon owner to understand the restrictions that prohibit the carrying of certain firearms onto federal property -- especially if the weapon owner frequently carries weapons on his or her person. Failing to understand these restrictions could result in falling into serious legal trouble with the federal criminal law system.

Here is a complete list of firearm items -- and other weapons -- that you are prohibited from carrying onto a federal facility:

• Anything that could be considered a dangerous weapon.
• Explosives and destructive devices, including their individual parts and components that could be converted into a dangerous weapon that would cause death, serious injury or property damage.
• Projectile weapons and firearms, including airguns, BB and pellet guns, antique firearms, flare guns, replica guns, toy guns, spearguns, starter pistols, stun guns and cattle prods, ammunition and slingshots.
• Bladed weapons of all types.
• Striking items like blackjacks and billy clubs.
• Disabling chemicals.
• Anything that could be used aggressively to cause harm to or immobilize someone.

This list applies to everyone who enters a federal facility -- such as contractors, occupants and visiting public -- except those officers who have the authority to carry weapons.

When police accuse suspects of theft crimes, the accused faces serious offenses that could come with stiff penalties in the event of a conviction. However, a theft crime is nothing compared to the crime of murder in terms of potential consequences.

As such, if prosecutors have included a murder charge with your theft charges, you will want to take your criminal defense process very seriously. There are numerous legal strategies that might be available to a murder defendant.

Consider the potential of an insanity defense. If an individual kills another person, and he or she was insane at the time, or if he or she was not cognitively able to understand what he or she was doing or that it was wrong, then the defense of insanity could be suitable. The insanity defense is often supported by psychological expert witnesses who render their opinion as to the psychological state of the accused individual.

Under the Second Amendment, the United States Constitution states that American men and women have the right to bear arms. More specifically, the constitution states that "the right of the people to keep and bear Arms shall not be infringed." The Second Amendment cites the need for a militia in order to secure the freedom of the state as the reason for this amendment.

By virtue of the second amendment, gun owners in Wisconsin and other states cannot have their firearms forcibly taken away from them in most cases. Furthermore, gun owners will often cite their Second Amendment rights when they speak up about gun restrictions, which many gun owners feel are unfair and unlawful. That said, the Second Amendment does not prevent Americans from getting into trouble with gun laws. For example, gun collectors, gun dealers and gun owners all need to adhere to federal and estate laws when possessing and handling their weapons.

With specific regard to federal gun laws, let's take a look at the most relevant restrictions against owning or possessing a gun under federal laws:

Not all theft accusations are appropriate. Sometimes, people are in the wrong place at the wrong time, or it just appears as if they stole something when they really did not. Regardless of how your theft charges came about, one of the following four theft defense strategies might apply to your circumstances.

Claim that the property belonged to you

Imagine you and a friend have a disagreement about who owns a specific piece of property. You decide to take the property home with you even though there's a disagreement, and your friend calls the police. If you can offer evidence that the property was yours -- perhaps by showing a receipt of purchase -- you will have an excellent criminal defense.
