MSNBC panelists on "Chris Jansing Reports" suggested efforts to "dehumanize" illegal immigrants contributed to a deadly shooting at an Immigration and Customs Enforcement (ICE) facility in Dallas Wednesday.At least three people were shot, two of them killed, after a gunman opened fire at the site. The FBI said it is investigating the incident as a "targeted attack" against ICE after uncovering anti-ICE messages written on bullet rounds found near the shooter.Jansing asked one of her guests, former ICE assistant chief counsel Veronica Cardenas, about the difficulties ICE agents face today, but Cardenas instead blamed rhetoric used to "dehumanize noncitizens" rather than the dangers ICE agents face.TOM HOMAN CALLS OUT 'MORNING JOE' HOST FOR ACCUSING ICE AGENTS OF DISAPPEARING PEOPLE"It is very difficult," Cardenas said. "It has been a very divisive environment. And the rhetoric does have to stop. Just yesterday, Homeland Security released a propaganda video on their social website stating or using Nintendos Pokmon to catch them all and continuing to dehumanize noncitizens."So, how do we fix this?" Jansing asked. "Or at least start to fix this? Because at least both sides say they want to bring down the temperature."The way you fix this is by really ensuring that due process is played out in these arrests, in targeting noncitizens," Cardenas said. "When you read about people being arrested, noncitizens being arrested, its already stated illegal."Like, that is something to assume. Its not allegedly. And, so, creating that where people, noncitizens, are already guilty until proven innocent, gives others this right, this hatred to attack and to justify what theyre doing to noncitizens. And, so, there has to be accountability and responsibility on both sides."MSNBC CONTRIBUTOR CLAIMS 'DARK' TRUMP SUPPORTERS ENJOY WATCHING ICE ACT LIKE 'SLAVE CATCHERS'Jansing turned to MSNBC national security analyst Christopher OLeary about reports that bullet rounds recovered from the shooter contained anti-ICE messaging. OLeary similarly argued that the attack stemmed from a "real or perceived grievance" from ICE tactics."We have a decade of intentionally attacking institutions, disinformation, misinformation, conspiracy theories, which led to polarization in society. All of those things have set the conditions for where we are now. And then you throw in the aggressive tactics that ICE has employed and the wearing of masks. Thats where you get political violence coming from," OLeary said."Political violence doesnt happen in a vacuum. Its in response to a real or perceived grievance that somebody has. And they think that this is the best outlet, and that is not justifying it. Its just where you see these pockets of violence emerge. Its in response to something."MSNBC REPORTER DEFENDS ILLEGAL IMMIGRANTS AS THE 'FABRIC' OF LOS ANGELES WHILE ANTI-ICE RIOTS CONTINUEFox News Digital reached out to MSNBC for comment.The MSNBC segment followed a press conference with Joshua Johnson, an acting field office director who criticized the rhetoric targeting ICE agents.CLICK HERE TO GET THE FOX NEWS APP"The rhetoric has to stop.
