Authorities say the gunman suspected of killing nine and injuring 27 in Munich on Friday was obsessed with mass shootings and had a history of psychiatric problems.
The shooting came as a shock to Germany, a country with typically low levels of gun violence.
"If there are no terrorist links to this attack, there might be very little they can actually do. There are fairly strict gun laws in Germany," Politico's Matthew Karnitschnig told CNN.
Despite early reports of multiple shooters, police say the suspect acted alone and wasn't connected to terrorism.
The gun laws in Germany are noticeably tighter than what you see in the U.S.
Citizens have to have a specific reason for owning a gun and have to pass tests to buy a firearm.
You can buy a gun in the country at 18 years old, but anyone under 25 must undergo a psychiatric evaluation.
Authorities say the suspect was an 18-year-old student and armed with a 9 mm Glock pistol and 300 bullets. He was also under psychiatric care and receiving treatment for depression.
Authorities haven't said how the shooter got the weapon used in the shooting.
