In 1925 Khoe was arrested in a high-profile Persdelict (press offense) case for an article he published which criticized the hate speech laws in the Indies which fell very harshly upon native and Chinese editors and writers.
[3] His case itself was not noteworthy, but rather his poor treatment in the prison in Glodok became the subject of discussion in the Dutch language press of the Indies, which took offense at the sight of a 20-year-old journalist being paraded in front of the public in shackles and chains without having been found guilty of anything.
[7] In the spring of 1932 another editor of Keng Po, Tan Boen Soan, left to become editor-in-chief of a competing paper, Warna Warta.
[9] In early 1939, two editors of Keng Po, Zain Sanibar and Injo Beng Goat were brought to court under a Persdelict (press offence) over an article they had printed about the Regent of Pandeglang a year earlier.
[10] Almost immediately Injo was brought before the court once again for an insulting article he printed about Adolf Hitler, calling him a fool who had been unpopular in school, bad with women, constantly having suicidal thoughts, an illegitimate child, and so on.
