Is Nigeria turning into a dictatorship?

There has been a lot of arrests going on in Nigeria since our self righteous President Muhammadu Buhari came into government. A lot of them for a good cause. But it is worrying how these arrests are being carried out by agents of the government EFCC or DSS.  Another worrying part is the disobedience of court order. Then how come it is mostly members of the opposition parties that are mostly indicted, especially the very loud ones. But the most worrying side of it is how the president remains quiet in the mist of all these court order violations. My point, is that investors use these as criteria to know a safe country to invest in and with these actions, is it safe to invest in Nigeria, right now? This government should should look at all aspect of the consequences of their actions, because Nigerians are not blind to all this. Already from every indicators and mathematics APC will not win in 2019, but they should not make it easy for the opposition.
