As violent clashes continue between law enforcement and protesters in Portland and around the country, debate is swirling around how police can cut back on lethal force. Some companies are stepping up to offer new high-tech tools like remote handcuffs for police to use instead of the more dangerous options like pepper spray, rubber bullets and flash grenades.

Human rights group Amnesty International analyzed 500 videos from protests from May 26 through June 5 and found 125 incidents of excessive force across 40 states and the District of Columbia.

"We saw a misuse of tear gas, pepper spray, pepper balls, 40 millimeter impact rounds, basically every combination of less-lethal weapon being used in inappropriate ways," said Amnesty International weapons investigator Brian Castner.

Still, some insist that having options is important for avoiding the need for a firearm. "All of these devices should be at hand for the cops to use other than deadly physical force being used by a firearm because it's the only profession in America where the citizens give you the right to take your life," said Corey Pegues, former New York Police Department Deputy Inspector.
