50 US law enforcement agencies use radar to see inside homes

The US has secretly equipped at least 50 law enforcement agencies with radars that enable their officers to see through the walls of the houses
​

The agencies, including the FBI and US Marshals Service, began using the handheld Range-R devices more than two years ago without public disclosure, USA Today reported.

Using the device enables the officers to determine the number of the people in a house and their locations. The device uses radio waves to detect motion as slight as human breathing from more than 50 feet away.

The use of the surveillance device has raised questions about Fourth Amendment protections against unwarranted police searches.

"Technologies that allow the police to look inside of a home are among the intrusive tools that police have," said Christopher Soghoian of the American Civil Liberties Union (ACLU).Earlier in 2001, the Supreme Court said that police normally need a search warrant before they may draw upon thermal cameras and advanced radar sensors.

"The idea that the government can send signals through the wall of your house to figure out what's inside is problematic," Soghoian said."Technologies that allow the police to look inside of a home are among the intrusive tools that police have," he added.

A Marshals Service spokesman, however, claimed that the device has been used to arrest dangerous criminals "based on pre-established probable cause in arrest warrants."Since 2012, the agency has spent at least $180,000 on the devices, according to federal records.SB/AGB

Wenzetu wanawekeza kwenye technologia sisi je?Us pia wako na project ya "invisible soldier" wanatengeza vitu maalumu ili wanajeshi wao wasiweze kuonekana,hapa wanasema wancheza na "properties of light".Ikifika huku bongo itakuwa balaah,unamfuatilia mtu huku uonekani ukifika unajimake visible.

nchi zinazojua nini maana ya sayansi na teknolojia wanawekeza zaidi katika nyanja hiyo nchi ambazo haziju zinawekeza zaidi katika siasa

Thats why US is big brother

Mkuu hawa wameanza toka zamani, ndio maana wanatunyanyasa

Mmh!! Mi najiuliza tu kuhusu hicho kifaa kinachoweza fatilia yanayoendelea ndani ya nyumba, hivi hawa jamaa si wakakuona uchi wako ata kama umevaa nguo?, hii si hatari jamani.

Hiyo ya kufanya mtu awe invisible ni rahisi sana kuichakachua, ukiwa na infrared sensor utaweza kirahisi kabisa kujua hapa kuna binadamu kutokana na heat signature, tatizo linakuja kukiwa na heat sources kila kona au nchi zenye joto kali zaidi ya human's body temperature hii njia inakua mziki, option labda kwenda na motion sensors japo itadetect all kinds of motions hadi iwe regulated kuestimate motion ya heavy objects kama binadamu say 60kg+ from other simple objects kama nyasi etc.....

Hilo la kudetect motion ya watu ndani ya nyumba sioni cha ajabu hapo hiyo ni technology ambayo ilikuwepo miaka na miaka, kusema wameanza kuimplement two years before nadhani ni fix, hii nahisi inaenda back to 10 years kabisa, its a very simple project ambayo serious engineers ukiwakalisha hata watatu wanatengeneza..
