>> reporter: the review is an acknowledgment that government officials need to be more sensitive to the families of u.s. hostages abroad. families have complained that they feel like they're not receiving timely information like they're being dragged through the bureaucratic process, and in at least one, case, with the family of murdered journalist james foley they were threatened withec prosecution if they tried toso make a ransom payment to rescue their loved one. >> my message to my beloved parents. >> reporter: his mother diane foley told cbs news the changes are a positive step but a baby step. and that she's been working with u.s. officials conducting the policy review. while the obama administration will still retain a no-ransomff policy, a u.s. official says thel review will likely recommendne that families not be threatened with prosecution. also, they will work directly with a broader group of government officials fromnt relevant agencies including the state department and the fbi instead of the case officer currently assigned to families. officials are also determining the best way to share

intelligence with families including, for example, hostage whereabouts which is often classified. in terms of timing, the dramatic turn of events last week with news of warren weinstein's death might have actually slowed down the review process. but jeff, the u.s. official says it will likely be completed within weeks, not months. >> glor: all right, julianna thank you. american law enforcement officials have been warned of a possible isis terror plot against the u.s. military and law enforcement officials, jeff pegues is following this. jeff, what we know? ta >> reporter: this is a warning that went out to law enforcement across the country on friday. authorities have not identified any specific suspects or targets. but information from communication involving known isis associates overseas specifically mention the statecr of california. and as a result of that,te security has been ramped up atin airports across that state.ab jeff, since last summer, western intelligence has been concerned about a threat to aviation. >> glor: jeff, any idea if this

means an increased danger posed by isis? >> reporter: even though this is a warning that was put out on friday, these are not new threats. for some time now isis has been attempting to inspire lone wolf attacks here in the u.s. the department of homelandit security says it will adjustsa security measures as necessary. it has already enhancedg screening at select overseasts airports and increased random searches of passengers and carry on luggage on flights headed to the u.s.. >> glor: jeff pegues in d.c. jeff, thank you very much. the u.s. has confirmed russian hackers read some of president obama's e-mails when they breached the white house archives last year. those e-mails were unclassified. officials say no classified e- mails were compromised. in baltimore today, it was the wake of freddie gray, the 25- year-old who suffered a fatal spine injury in police custody. it has been a weekend of protests, sometimes violence. mark albert is there. >> reporter: mourners carry flowers and grief into a funeral home in north baltimore today in memory of freddie gray. jeanette johnson was one off hundreds who came. >> i'm just so devastated about this.

>> reporter: did you know freddie gray. >> no. >> reporter: and yet are you personally devastated. >> yes, yes.am because i have sons.te i have two sons, you know. it could have been one of them. >> reporter: jasmine lee is freddie gray's cousin.w. >> when i go in there, it's reality that he's really gone. >> reporter: gray's still unexplained death a week ago after suffering a spinal injury in police custody lead to an eruption of anger which untilin yesterday had remained largely peaceful. but 90 minutes before dusk a mob near the camden yards baseballca stadium attacked police cars threw bottles, rocks and cones at police and looted several nearby businesses. dozens of officers charged the rioters, surging into the crowd to detain a protestor. 35 were arrested in all. as night fell, 1,200 officers were deployed city wide, 300 swept the downtown streets. we spoke to lieutenant thompson who declined to give his first t name. do you believe these are outsiders?

>> i have dealt with the people in this neighborhood for yearsoo and i have never had any trouble like this. >> reporter: freddie gray's twin p sister frederica later joined the city's mayor to call for peace. >> you can all please, please, stop the violence. freddie gray would not want this. >> reporter: damaged businesses like this one spent the day boarding up smashed windows. freddie gray's family has asked that there be no protests today or tomorrow when the funeral is scheduled. jeff? >> glor: mark albert in baltimore, thank you. two people are dead and severalen t missing after a powerful stormrt capsized at least ten boatsra during a regatta in alabama's mobile bay. here's jericka duncan. >> reporter: they could see thes ominous clouds looming behind their boat. >> the winds are catching us now. >> reporter: as the storm moved closer, the waves intensified. boats buffeted from side to side as 70-mile-per-hour wind gusts whipped through the middle of mobile bay late saturday afternoon. one man reported seeing boats

sink so fast, that people didn't have time to grab life preservers. randy rutledge and his girlfriend say they were in the water for two hours before being spotted. >> the storm just subsided just enough that i could keep my head up. and not drink too much salt water. but-- i had no choice but to hang on to that cushion, mainly because i had to find her. >> reporter: officials say ten. boats overturned. at least 40 people have been rescued. airplanes and rescue boats havere covered more than 1,700 square miles of the bay in search of survivors. u.s. coast guard captain duke walker praised several local agencies for their help. >> without their efforts, thisy tragedy would have been far greater. >> reporter: boaters say the storm was unusual because the high winds lasted 30 minutes.

scattering boats and complicating search-and-rescueef efforts. despite warnings from the national weather service about the storm, more than 100 sailboats participated in an annual regatta. today we spoke to organizers whoco would not comment, jeff, oner whether there were ever any plans to delay or cancel the event. >> glor: all right, jericka duncan, thank you very much. the aurora movie theater gunman is about to go on trial. how will his insanity defense hold up. and the president holds no punch lines at the so-called "nerd prom." when the "cbs evening news" continues. nerd prom. when the cbs news continues. one helps keep you awake- the other helps you sleep. science suggests when you have insomnia, the wake system in your brain may be too strong and your neurotransmitters remain too active as you try to sleep, which could be leading to your insomnia. ohh...maybe that's what's preventing me from getting the sleep i need!

though the passage of time since the july 2012 shooting may help james holmes because it's given time for passions to cool. but justice delayed can fuel its own kind of anger in a traumatized community, says nancy leong, professor of law at the university of denver. >> the community may be quite resentful about the fact that it hasn't had the opportunity to heal that there hasn't been any kind of closure as a result ofth the trial. >> reporter: the key issue, was he insane when he pulled the trigger over and over. it's a difficult defense to pull off, more so in this case. the jury is going to see horrific pictures of what he did. does that overwhelm their instinct to feel sympathy or mental instability? >> i think it has to. we all go to movie theaters, anybody can imagine themselves in this situation. >> reporter: it's scary to all of us. >> it is scary to all of us because this is a situation in which we could all imagine the gunfire starting. i think that that is a really frightening possibility for a

lot of people. and surely that has to have an emotional impact on the jury. >> reporter: when holmes appears in the courtroom here at the arapahoe county courthouse, one thing that could influence the jury is quite literally, how hera looks. >> he had orange hair, he looked like a clown, literally. >> reporter: he went from that orange hair to bearded and a far more normal look. jury experts like jessica brylo says looks can matter a lot. >> the more crazy he looks, the less that he can bond with the jury, the more that they will see him as an outsider and different from them.th that can help in the sense that people might see him as being insane. m but it may not help in the sense that then they don't feel like he could be rehabilitated and put back on the street. >> reporter: so that doesn't actually help the insanity defense that you look a little strange? >> it is a gamble. it could go either way. >> reporter: the one thing even the defense does not dispute is that holmes did it. the only real question for the jury is, how will he pay for it.
