- Idara ya polisi nchini imelaumiwa kwa muda mrefu kutokana na visa vya mauaji ya kiholela, utepetevu na ufisadi miongoni mwao.(Solved)
Idara ya polisi nchini imelaumiwa kwa muda mrefu kutokana na visa vya mauaji ya kiholela, utepetevu na ufisadi miongoni mwao.Ni kutokana na kilio cha mwananchi pamoja na mashirika yasiyo ya kiserikali ambapo serikali imejitolea sabili kubadili hali katika idara hiyo huku tume mbali mbali zilizobuniwa zikitoa mapendekezo muhimu ya kurekebisha idara hiyo. Matokeo ya hivi punde kutoka kwa shirika la Transparency International liliorodhesha idara ya polisi kama idara fisadi zaidi nchini,maoni ambayo yalisisitiziwa na shirika la kutetea haki za kibinadamu .Ufisadi bado umekita mizizi katika idara ya polisi tangu mabadiliko yaanze upande wa trafiki na hata ndani ya polisi,.Serikali imejitolea kupambana na ufisadi unaonekana kuwa kidonda ndugu katika idara ya polisi. Wananchi wanasema kuwa polisi ni mafisadi na kusahau kuwa ufisadi unashirikisha watu wawili na wote wanapaswa kufunguliwa mashtaka,lazima raia na polisi wazingatie hili.Na ili kuleta mabadiliko muhimu katika idara ya polisi,mapendekezo yote pamoja na ya tume zingine za hapo awali lazima yatekelezwa na kwa mujibu wa katiba mpya.Lazima mabadiliko yaanze kuanzia juu kwani maafisa wadogo hulazimiswa kuchukua hongo ili wapelekee wakubwa wao,ni lazima shughuli ya kuwachagua maafisa waliobora ifanyike kisheria ili mabadiliko yaanze kutoka kwa wakuu wa maafisa wa polisi.
Polisi kidogo wameweza kubadili ile lugha yao ya matusi na ukali kwa rai.Raia nao hawajabadilika,bado wana uwoga dhidi ya polisi na itachukua muda kwani wanadhania kuwa kikosi ni kile kile cha kitambo.Kwa upande wa polisi, hakuna mageuzi yamefanyika.Unaposafiri kuja mjini polisi wangali wana chukua hongo kutoka kwa wenye matatu na kuwaruhusu kubeba kupita kiasi, pia usalama umedorora sana kwani kumekuwa na visa vingi vya mauaji hapa mjini.ukiangalia maafisa wa polisi hakuna mageuzi makubwa yameshuhudiwa haswa kwa upande wa maafisa wa trafiki bado ni wale wale na ufisadi ungali upo.
Mabadiliko ambayo tunataka ni ile polisi wasikae mahali kwa muda hadi wanajuana na mafisadi na majambazi.Maafisa wa polisi wanafaa kuhudumu katika kituo kimoja kwa muda usiozidi miaka mitatu.Kwa kufuata njia hiyo mabadiliko yatapatikana.Juhudi nyingi zikielekezwa katika kubadili kikosi cha polisi wananchi wanapaswa kuhamasishwa ili nao wawezakubadilikahaswa kuhusuiana na mtazamo wao kwa maafisa wa polisi .Na huku tukijaribu kubadili maafisa wa polisi wananchi pia wanapaswa kuelimishwa ili waweze kubadili mtazamo wao kuhusu maafisa hao.Ni bayana kuwa ili kuweza kuleta mabadiliko ya kutamanika katika kikosi cha polisi na haswa katika kupambana na ufisadi uliokita mizizi wananchi sawia na maafisa wa polisi wanajukumu la pamoja kuleta mabadiliko hayo yatakayopelekea kuwepo kwa mlahaka mzuri kati ya maafisa wa polisi na raia.Hatimaye kuwepo kwa huduma bora itakayochangia pakubwa kuboresha uchumi wa taifa na kuafikiwa kwa ruwaza ya mwaka 2030.
