"There appears to be no regard or concern with anybody taking their photograph, or videoing them," said Rialto PD Capt. Anthony Vega about the two thieves who wore gloves and face masks. "They're definitely not afraid of anybody confronting them."
Police believe the same two thieves then burglarized another Walgreens store in Rialto, and a third Walgreens store in Colton.
"It appears to be the same suspects that came in and removed the items in the same exact manner and walked out casually with a little over $1,000 worth of beauty supplies," said Vega.
He said Rialto police detectives are investigating nearly a dozen of these kind of incidents in the city over the past year. But it's not a situation unique to the Inland Empire.
Over the past several months, videos posted to social media have gone viral showing violent smash-and-grab operations all across the state, many in which the thieves storm into stores, break through counters to steal expensive merchandise and then run away.

Many in law enforcement blame recent controversial changes to state law, such as Proposition 47, as contributing factors to the rise in these kinds of property crimes.
"It's something that people in law enforcement and the community have been dealing with for years. We have lesser or reduced penalties on criminal offenders, and at this point that have nothing to lose," said Vega. "They're not going to spend a lot of time in jail. They're going to get a citation and be released, and they'll be right back at it that evening committing the same crimes."
Rialto police are in the process of assembling a special team to address these type of incidents at retail stores within the city limits.
Vega said the best thing bystanders can do if they see an incident like this in progress is to safely record video of the incident - if possible - and call police.
"Definitely be a good witness," said Vega. "At the end of the day, we're talking about this because somebody had the wherewithal to take video of it and get some pertinent information for us. So if they can get a safe picture, or video of a license plate leaving, that's really helpful for us."
